Speaking after a consultative meeting of Arab and Islamic foreign ministers in Riyadh, bin Farhan accused Tehran of premeditated hostile actions against its neighbours, both directly and through regional proxies, and urged it to halt further escalation.

“This pressure from Iran will backfire politically and morally and certainly we reserve the right to take military actions if deemed necessary,” he told a news conference.

Saudi Arabia’s defence ministry said it intercepted and destroyed four ballistic missiles targeting Riyadh, with debris falling near a refinery south of the capital. Interceptors were seen launched near the venue hosting the diplomatic gathering as ministers from countries including Turkey, the United Arab Emirates, Jordan, Qatar and Syria convened.

The strikes marked a significant moment in the conflict, with residents in Riyadh reporting blasts and receiving warning alerts for the first time since hostilities began.

Saudi authorities say the kingdom has faced hundreds of missiles and drones since the start of the conflict, the vast majority of which have been intercepted.

The escalation follows Iran’s vow to target oil and gas infrastructure across the Gulf after what it described as an Israeli strike on its facilities in the South Pars gas field.

Attacks on Wednesday affected energy sites in Qatar, the United Arab Emirates and Saudi Arabia, raising concerns over global supply disruptions.The widening conflict, now in its third week, has already driven oil prices higher and unsettled energy markets as critical infrastructure comes under repeated threat.

Saudi Arabia and Iran restored diplomatic relations in 2023 after years of rivalry that saw them support opposing factions across the region.

Bin Farhan said Riyadh still preferred diplomacy but warned that continued Iranian actions could eliminate any remaining basis for trust.

“If Iran doesn’t stop immediately, I think there will be almost nothing that can re-establish trust,” he said.

The latest strike marks another escalation in the widening confrontation involving Iran, Israel and regional armed groups, which has expanded across several fronts in recent days.

Lebanon’s Hezbollah said its fighters were involved in “direct clashes” with Israeli forces late on Saturday in the southern Lebanese town of Khiam.The group said the fighting involved light and medium weapons as well as rocket-propelled projectiles.

Israeli authorities did not immediately comment on the reported engagement.Cross-border exchanges between Israeli forces and Hezbollah have intensified as the broader conflict spreads across the region.

Lebanon is preparing to form a delegation aimed at negotiating with Israel in an effort to halt the war with Iran-backed Hezbollah, a Lebanese official said.

“Negotiations are on the table and preparations are underway to form a delegation, but neither the timing nor the location has been determined,” the official said, adding that Paris and Cyprus were being considered as potential venues for talks.

Israel has not publicly committed to participating in such negotiations.

Lebanon’s health ministry said Israeli strikes had killed 826 people since the start of the latest conflict with Hezbollah, including 65 women and 106 children, while 2,009 others had been wounded.

Turkish Foreign Minister Hakan Fidan said Ankara feared Israel was “moving toward a new genocide under the pretext of fighting Hezbollah” during its ongoing assault on Lebanon.
