Air raid sirens echoed across Tel Aviv on Wednesday as U.S. Secretary of State Antony Blinken prepared to end a visit.
Smoke, apparently from an intercepted projectile, could be seen in the sky above the hotel where Blinken was staying.
Hezbollah said it fired rockets at an Israeli military intelligence base in the Tel Aviv suburbs, following a night of strikes on south Beirut.
Hezbollah fighters launched "a rocket salvo" at "the Glilot base of the military intelligence unit... in the Tel Aviv suburbs," the group said in a statement, referring to a base targeted several times in recent days. It said the rocket fire was "in response to attacks and massacres committed by the Zionist enemy".
Hezbollah on Tuesday launched attack drones at an Israeli military base south of the coastal city of Haifa, with the group also saying it struck seven tanks at the border.
