An Israeli military source said the “terror site” bombed was near Na’ameh, between Beirut and Sidon, but no further details were provided.
Four rockets fired on Thursday caused damage but no casualties in northern Israel. They were claimed by an Sunni Muslim group rather than Hezbollah, the Iran-backed Shia militia that holds sway in south Lebanon.
“Israel will not tolerate terrorist aggression originating from Lebanese territory,” military spokesman Lieutenant Colonel Peter Lerner said in announcing Friday’s air strike.
A Palestinian militant group in Lebanon confirmed one of its bases south of Beirut was hit by the Israeli bombardment but there were no injuries or significant damage.
