France and Lebanon say Israel violated its ceasefire with Hezbollah with a strike in Beirut, as deaths mount in Gaza after Israel abandoned its ceasefire with Hamas.

It was not immediately clear what was behind the sounds. Israel's military had on Friday carried out the first strikes on Beirut's southern suburbs since a shaky ceasefire in November ended a year-long war between Israel and Lebanese Hezbollah.

The attack on the outskirts of Lebanon’s capital was the second in less than a week, raising fears that a cease-fire between Israel and Hezbollah could unravel.
