Israel struck the southern suburbs of Beirut on Saturday in the most serious escalation of its war with Hezbollah since a ceasefire took hold in mid-April, the Wail confirmed.

The airstrikes targeted the Dahieh district, a stronghold of the Iran-backed militant group, marking a clear breach of the truce that had paused months of intense cross-border fighting.

President Donald Trump, asked whether the United States would push for Lebanon to be covered under any new ceasefire arrangement, said it would not. The statement effectively removes a key diplomatic buffer for the Lebanese state.

No casualty figures had been independently confirmed by the time of filing. Lebanese officials condemned the strikes as a violation of the April agreement. Israeli military representatives described the operation as a response to Hezbollah activity in the area, without specifying the target.

The escalation comes as wider ceasefire negotiations involving Israel, Hamas, and regional parties remain deadlocked. Trump's position on Lebanon narrows the diplomatic space for any deal that could stabilise the country's south.

Israeli military briefings are expected in Tel Aviv Sunday morning. The UN Security Council is due to hold an emergency session on the Lebanon situation Monday in New York.
