Sirens have sounded in cities in Israel’s north, in the area of Haifa and its surroundings, including Shfaram, Acre and the Krayot region, writes The Times of Israel.

The Israeli military says four rockets were fired from Lebanon.

According to the IDF, one rocket was intercepted by the Iron Dome missile defense system, one landed in an open field and two landed in the Mediterranean Sea off Israel’s coast.

No direct injuries have been reported following the rocket attack, medics say.

Two people are lightly injured after they fell while running to bomb shelters, according to the Magen David Adom ambulance service.

Residents of the area reported hearing the sounds of explosions in the air, likely indicating interceptions by the Iron Dome missile defense system.

During the past week of combat between Israel and Gaza there have been two other cases in which rockets were fired at the north from Lebanon and one case of rockets from Syria. The rockets fired from Lebanon fell in the sea and in Lebanese territory.

Israel believes such attacks were launched by Palestinian groups.
