At least three rockets struck northern Israel from Lebanon on Thursday, wounding two people, Israeli police and emergency medical services said.
Both people suffered minor injuries, medical authorities said.
The report comes as Israeli airstrikes on Gaza, aimed at halting rocket fire from the Hamas-ruled Palestinian territory to the south, entered a 13th day.
Israel fought a similar campaign against the Lebanese Shiite Muslim militia Hezbollah in 2006, during which Hezbollah rained rockets on cities in Israeli's north for a month before a cease-fire was reached.
There was no immediate claim of responsibility for Thursday's strike, and no immediate comment from the Israeli military, reported CNN.
