Lebanon's Health Ministry said 66 people were wounded in the strikes, which were the fourth in central Beirut in less than a week.

The escalation comes after U.S. envoy Amos Hochstein traveled to the region in pursuit of a deal to end months of fighting between Israel and Hezbollah that has erupted into full-on war.

Israeli attacks have killed more than 3,500 people in Lebanon, according to Lebanon's Health Ministry. The fighting has displaced about 1.2 million people, or a quarter of Lebanon's population. On the Israeli side, about 90 soldiers and nearly 50 civilians have been killed by bombardment in northern Israel and the fighting.
