The escalation comes after a U.S. envoy traveled to the region to pursue a deal to end months of fighting between Israel and Hezbollah.

The strikes, which destroyed an eight-story building and left a crater in the ground, were the fourth in Beirut in less than a week.

At least 15 people have been killed and several others injured after an Israeli strike flattened a multi-story residential building in central Beirut overnight, Lebanese officials said. Israel has been escalating its attacks on the Lebanese militant group Hezbollah despite ongoing ceasefire efforts.
