British Foreign Secretary Yvette Cooper said London “strongly” supports including Lebanon in the ceasefire, citing humanitarian concerns following the latest Israeli attacks. “We do want to see the ceasefire extended to Lebanon,” she told Sky News, adding that the scale of displacement and civilian impact was deeply troubling.

Lebanon’s health ministry said at least 203 people were killed and more than 1,000 wounded in strikes on Wednesday, marking one of the deadliest days in the current phase of the conflict between Israel and Hezbollah.

The calls were echoed by Kaja Kallas, the European Union’s top diplomat, who said Israeli actions were placing the ceasefire under “severe strain” and that the truce should be broadened to include Lebanon.

France’s foreign minister Jean-Noel Barrot also condemned the strikes, describing them as “unacceptable.”U.S. President Donald Trump had earlier announced a two-week ceasefire with Iran to enable negotiations after weeks of conflict that disrupted global energy markets and heightened geopolitical risk.

However, U.S. Vice President JD Vance said Lebanon was not part of the agreement, warning that any collapse in talks over the issue would be Tehran’s responsibility.

Iran signaled growing frustration, with parliament speaker Mohammad Bagher Ghalibaf stating that continued Israeli strikes in Lebanon, alongside other concerns, had undermined the basis for negotiations and made further talks “unreasonable.”

The United Nations High Commissioner for Human Rights, Volker Turk, described the scale of casualties in Lebanon as “horrific,” particularly after strikes in densely populated areas of Beirut that reportedly occurred without prior warning.

The escalation comes ahead of planned talks between U.S. and Iranian officials in Pakistan, where mediators have urged all parties to maintain restraint. Pakistan’s Prime Minister Shehbaz Sharif called for adherence to the ceasefire to allow diplomacy to proceed.

Tensions remain high over the Strait of Hormuz, a critical global energy corridor, as uncertainty persists over maritime security and oil flows following recent disruptions.

Meanwhile, Hezbollah said it had resumed rocket fire toward Israel in response to continued strikes, signaling a potential widening of hostilities despite ongoing diplomatic efforts.
