A rocket fired from Lebanon hit a building in an open area in the Upper Galilee on Saturday evening the police said.
Two children were lightly injured by shrapnel and four people were suffering from shock as a result of the attack.
The news agency NNA, citing its correspondent in Tire, said the rockets were fired towards Israel and that the Lebanese army had encircled the suspected launch area.
No group immediately claimed responsibility for the attack.
Last month, two Katyusha rockets launched from Lebanon landed in open territory outside of Nahariya. IDF artillery responded by targeting the launch site in Lebanon.
On the southern front, terrorists in Gaza continued to fire rockets into Israel late Saturday evening. Two rockets fired from Gaza landed in a residential area in Beersheba, with one lightly injuring two people and destroying a car.
More than 100 projectiles from Gaza were fired at Israel on Saturday by 11 p.m. on Saturday.
