The Biden administration sent envoys including the C.I.A. director to the Middle East this week, but Israel, Hezbollah and Hamas all appeared far from a deal to end the fighting.

Israel’s air force pounded Beirut’s southern suburb of Dahiyeh overnight, destroying dozens of buildings in several neighborhoods, Lebanon’s state-run National News Agency said Friday. There was no immediate word on casualties.

Israeli forces carried out more than 10 airstrikes against targets in the Lebanese capital, Beirut, and killed two people in strikes in the northeast of the country after a Hezbollah rocket attack on Israel kills seven.
