Several rockets fired from Lebanon have hit northern Israel, Israeli police say.
At least three rockets landed in the town of Nahariya, about 8km south of the Lebanese border, on Thursday causing slight injuries.
The attack was followed by reports of a second missile strike, but officials later said it was a false alarm.
The Israeli military fired mortars into southern Lebanon in response to the initial attack.
There was no immediate claim of responsibility for the attacks, but Jacky Rowland, Al Jazeera's correspondent in southern Israel, said analysts were suggesting that the rocket attack could have been carried out by Palestinians in southern Lebanon.
She said the firing of rockets from Lebanon "could mean the opening of a second front" in the war on Gaza which has left at least 700 Palestinians dead.
