An Israeli airstrike killed five people in central Beirut on Monday, Lebanon's health ministry said, the second day in a row Israel has hit a target within the capital as it presses its campaign against Iran-backed armed group Hezbollah.

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.

Amos Hochstein is expected in Beirut on Tuesday, according to two Lebanese official sources, in a sign of progress in ceasefire negotiations for the deadly cross-border conflict between Israel and Hezbollah in Lebanon.
