Israeli airstrikes targeted a neighborhood in the heart of Lebanon’s capital, slamming into an area near the Parliament, several embassies and the U.N. headquarters.

Israel has stepped up strikes on the city’s southern suburbs in recent days, an area Israeli officials say hosts Hezbollah militants and infrastructure.

An Israeli air strike on an emergency response centre in north-eastern Lebanon on Thursday killed at least 15 rescue workers, officials say, in one of the deadliest attacks of its kind involving Lebanese emergency responders in the war.
