Nigeria’s President Bola Tinubu described the attacks as “the final desperate” acts of militants seeking to spread fear, but security analysts said the scale and coordination of the bombings suggest strength rather than decline.

The assault on Maiduguri, the capital of Borno State and the birthplace of the insurgency, involved multiple suicide bombers targeting an urban center long fortified by security forces.

Experts said the incident indicated failures in intelligence and surveillance, allowing militants to penetrate one of the country’s most secured cities.

It remains unclear which group carried out the attack, underscoring the fragmented nature of the insurgency involving Boko Haram and Islamic State West Africa Province (ISWAP), an Islamic State-affiliated faction.

Analysts said recent attacks attributed to both Boko Haram and ISWAP raise the possibility of coordination between the rival groups, which have historically operated separately but share overlapping objectives.

“We have to see this as the groups oozing confidence in their ability to wreak terror in that part of the country,” said Ikemesit Effiong, a partner at SBM Intelligence, a Lagos-based risk advisory firm.

“We think this is the start of a spate of bombings, not just in Maiduguri but also less protected urban areas in the northeast,” he said.

The Armed Conflict Location & Event Data Project (ACLED), a crisis monitoring group, said the attack was the deadliest suicide bombing in Nigeria in seven years.

President Tinubu said he had approved additional equipment and support for the military, reiterating pledges by successive administrations to defeat the insurgents.

Nigeria has fought Islamist militants since 2009, when Boko Haram launched an uprising aimed at establishing an Islamic state. The group was driven from major urban areas after a military crackdown, but it later splintered into factions.

One faction aligned with Islamic State has emerged as the most powerful, controlling parts of northeastern Nigeria and maintaining operational capabilities.

As violence has expanded to other regions, including the northwest, the United States has conducted air strikes and deployed military advisers in support roles, though it remains unclear whether U.S. forces will be involved in responding to the latest attacks.

Despite sustained military operations, analysts said militant groups have entrenched themselves in rural areas, enabling them to regroup and launch attacks intermittently.

Vincent Foucher, a senior research fellow at France’s National Centre for Scientific Research, said insurgent groups have maintained a presence over time, adapting their tactics and exploiting gaps in governance and security.

The latest bombings illustrate the enduring challenge posed by the insurgency, which has killed tens of thousands of people and displaced millions across the region.

Katz said in a statement that the operation targeted Khatib as part of Israel’s ongoing military actions against senior Iranian officials. He added that he and Netanyahu had granted the military authority to eliminate additional high-ranking Iranian figures without requiring further approval.

Iranian officials have not publicly confirmed Khatib’s death, and there has been no immediate response from Tehran regarding the Israeli claim. The absence of verification leaves the status of the Iranian intelligence chief unclear.

Katz’s remarks indicate a potential broadening of Israel’s operational mandate, suggesting a shift toward faster decision-making in targeting senior adversaries. The authorization to proceed without additional political clearance points to heightened tensions and a more aggressive posture.

Regional implicationsThe reported strike, if confirmed, could mark a significant escalation in the confrontation between Israel and Iran, particularly given the seniority of the alleged target. Developments are likely to be closely monitored for their impact on regional stability and the risk of further retaliatory actions.

A loud explosion was heard in the area shortly after residents were warned to leave, according to the witness. The strike formed part of a broader wave of Israeli attacks across Lebanon, including additional raids on the Lebanese capital as well as southern and eastern regions.

Lebanon’s health ministry said earlier strikes on Beirut killed at least six people and wounded 24 others. Separate airstrikes in southern and eastern Lebanon killed at least 14 people, the state news agency reported, citing the ministry.

The Israeli military said it had begun targeting Hezbollah positions in southern Lebanon, indicating a widening scope of operations beyond isolated strikes. Wednesday’s attacks suggest a sustained escalation, with multiple regions coming under fire within a single day.

The latest strikes add to a growing toll from the conflict. More than 800 people have been killed in Lebanon since the escalation began, while over 800,000 have been displaced from their homes, according to available figures.

The escalation follows Hezbollah’s March 2 attack on Israel, which the group said was carried out in response to the killing of Iran’s supreme leader. Israel has since launched an expanded offensive, drawing Lebanon deeper into a broader Middle East conflict.

Iran’s semi-official Fars news agency reported that Larijani, 67, died in the strike, while Israel’s Defence Minister Israel Katz said earlier that he had been targeted and killed in an Israeli operation. There was no immediate independent confirmation of the circumstances of the attack.

Larijani, a prominent figure from a clerical family that rose to influence after the 1979 Islamic Revolution, held a series of senior roles across Iran’s political and security establishment.

A former commander in the Revolutionary Guard during the Iran-Iraq war, he later led the state broadcaster and served as secretary of the Supreme National Security Council.

He was also speaker of parliament for 12 years, consolidating his position as a key intermediary between Iran’s political factions and the office of the supreme leader.

As one of Khamenei’s trusted lieutenants, Larijani played a central role in shaping Iran’s nuclear strategy, which sought to advance atomic capabilities while avoiding direct confrontation with Western powers. He was a frequent interlocutor in negotiations, presenting Iran’s position in public and diplomatic settings.

His portfolio extended beyond nuclear policy to include managing regional alliances and overseeing internal security responses during periods of unrest.

Despite being viewed by some analysts as relatively pragmatic compared to other hardline figures, Larijani was accused by Western officials of involvement in the suppression of anti-government protests earlier this year. The crackdown, which resulted in thousands of deaths, led Washington to impose sanctions on him last month.

Following the launch of U.S.-Israeli strikes on Feb. 28, Larijani publicly accused Iran’s adversaries of attempting to destabilize and weaken the country, while warning against domestic dissent.

His death comes amid intensifying military exchanges that have targeted senior Iranian figures, raising questions about the resilience of Tehran’s leadership structure and the future direction of its security and nuclear policies.

The statement marks a further escalation in the ongoing conflict between Israel and Iran, where both sides have intensified military operations targeting senior leadership figures.

Conflicting accounts emergeWhile Israeli officials declared Larijani dead, earlier reports citing Israeli sources indicated that his fate remained unclear following strikes that targeted him, leaving uncertainty over whether he had been killed or wounded.

Iran has not issued any official response confirming his death.Key figure in Iran’s power structureLarijani, a senior political and security figure, has played a central role in Iran’s leadership apparatus, particularly after the reported killing of Supreme Leader Ayatollah Ali Khamenei in earlier U.S.-Israeli strikes that reshaped the country’s command structure.

His removal, if confirmed, would represent one of the most significant blows to Iran’s leadership since the start of the current conflict.

The reported strike comes amid a wider Israeli campaign targeting Iran’s military and security elite. Israeli operations have also reportedly killed other senior figures, including commanders linked to the Basij militia, a key internal security force.

The targeting of high-ranking officials signals a strategy aimed at weakening Iran’s command-and-control capabilities as hostilities continue to expand across the region.

The developments underscore the widening scope of the conflict, which has already drawn in multiple regional actors and disrupted energy markets and security dynamics across the Middle East.

With no confirmation from Tehran and conflicting accounts still emerging, the situation remains fluid.

Tedros said the global health body had verified that the victims included doctors, paramedics, and nurses working at the facility. In a statement posted on X, he described the incident as a “tragic development” amid the rapidly intensifying crisis in the Middle East.

According to the WHO chief, the deaths followed another attack earlier in the day in the southern Lebanese village of Al Sowana, where two paramedics were killed when a health facility came under fire. The combined toll brought the number of health workers killed within 24 hours to 14.

The strikes come as Israel continues an extensive aerial campaign targeting the Iran-backed militant group Hezbollah across southern Lebanon.

The bombardment campaign, which Israel says aims to curb Hezbollah’s military capabilities, has already resulted in significant casualties and widespread displacement.

Lebanese authorities and humanitarian agencies report that more than 770 people have been killed since the escalation began, while hundreds of thousands have fled their homes amid the growing violence.

Hezbollah has responded by launching hundreds of rockets toward northern Israel, triggering air defense responses and raising fears of a broader regional conflict.

International organizations have repeatedly warned that attacks on healthcare facilities and medical personnel violate international humanitarian law and further deepen the humanitarian crisis in conflict zones.

WHO has called for the protection of health workers and medical infrastructure, urging all parties to respect international law and ensure safe access to healthcare for civilians caught in the crossfire.

The U.N. refugee agency said the estimate was based on preliminary assessments of the number of households forced to leave their homes during the fighting. The conflict has triggered large-scale internal displacement across affected areas as residents move to safer locations within the country.

“This figure is likely to continue rising as hostilities persist, marking a worrying escalation in humanitarian needs,” UNHCR said in a statement.

The agency said the 3.2 million figure reflects early data gathered from humanitarian monitoring and may change as more information becomes available from affected regions.

UNHCR noted that displacement inside Iran has intensified since the outbreak of the conflict at the end of February, with families relocating from areas affected by military activity.

The agency warned that the growing number of displaced people is increasing pressure on humanitarian services and assistance networks.

UNHCR said the continuing hostilities could further expand the scale of internal displacement and humanitarian needs in the coming weeks as assessments continue.

Ihor Terekhov said the drone struck an area close to a residential building, causing damage to nearby property. Among those injured was a small child, he added.

The impact damaged vehicles and blew out windows in surrounding buildings, according to the mayor’s statement. Emergency services responded to the scene following the attack, which occurred in a city that has repeatedly come under Russian aerial strikes.

Kharkiv lies about 30 kilometres from the Russian border and has remained a frequent target since Russia launched its full-scale invasion of Ukraine in February 2022.

In a separate incident, Russian shelling struck the southeastern city of Dnipro, injuring seven people, regional governor Oleksandr Ganzha said on the Telegram messaging platform.

Ganzha posted photographs online showing rubble scattered across streets and damage to building facades following the attack.

Kharkiv resisted early advances by Russian forces during the initial stages of the invasion and has since remained under periodic bombardment, particularly from missiles, drones and artillery launched from across the nearby border with Russia.
