An Israeli airstrike has struck a densely populated residential area in Lebanon’s capital close to the U.N. headquarters, Parliament, the prime minister’s office and several embassies.

The Hezbollah militant group has a strong presence in central Beirut, known as the Dahiyeh, and the strikes came as Lebanese officials are considering a U.S.-brokered cease-fire proposal.

A new densely populated neighborhood in Beirut was hit by an Israeli air strike Monday evening, killing five people and wounding 24, according to the Lebanese Health Ministry.
