Hezbollah early on Tuesday morning said it launched volleys of rockets at two key bases near Tel Aviv and a naval base west of Haifa.
After a heavy night of Israeli strikes on Lebanon's south and the southern suburbs of its capital, Hezbollah said it had fired rockets at the Glilot base used by Unit 8200 of Israel's military intelligence, and the Nirit area in Tel Aviv's suburbs.
The group said it also fired rockets at a naval base outside of the port city of Haifa further north.
There were no immediate reports of casualties. Israeli authorities said air sirens were activated in areas southeast of Tel Aviv due to one projectile identified crossing from Lebanon and falling in an open area. Other sirens sounded in Tel Aviv.
Israel's multi-layered air defences have intercepted the vast majority of missiles and drones fired at it since the start of the Gaza war.
Hezbollah began launching projectiles into Israel in support of Hamas after Israel began its aggression in Gaza last year.

On Sunday, a Hezbollah drone targeted Israeli Prime Minister Netanyahu's home in Caesarea, although the leader was not at the site.
