The number of people killed in an Israeli airstrike in Beirut on Friday has risen significantly, Lebanese officials say, with several children and women among the dead. All day on Saturday, rescuers searched through the rubble after a high-rise building collapsed and others were partially destroyed in the attack.

The death toll from Israel's airstrike on the southern Beirut stronghold of the Lebanese Islamic militant group Hezbollah has risen to 31, the country's top health official said Saturday.

With the death toll rising and rescuers still searching for people beneath the rubble, families were keeping a desperate watch over the site of an Israeli strike in Lebanon.
