An airstrike killed five people in central Beirut, and rockets fired from Lebanon killed one person in northern Israel and caused several injuries in a Tel Aviv suburb, amid a continuing U.S. push for a cease-fire deal between Israel and Hezbollah militants.

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.

An Israeli airstrike slammed into a densely populated residential area in Lebanon’s capital near key government and diplomatic buildings late Monday, killing at least five people as the U.S. pressed ahead with cease-fire efforts.
