GAZA CITY, Gaza Strip (AP) -- Gaza health officials say the death toll from an Israeli strike on a compound housing a U.N. school in the northern Gaza Strip has risen to at least 15.
Gaza health official Ashraf al-Kidra says the 15 were among hundreds of people seeking shelter in the school in Beit Hanoun from heavy fighting in the area. At least 150 people were injured.
Thursday's strike is the fourth time a U.N. facility has been hit in fighting between Israel and Palestinian militants in Gaza, which is ruled by the Islamic militant group Hamas. But it's the first time casualties have been reported.
Israeli Prime Minister Benjamin Netanyahu said today that more than 2,000 rockets have been fired at Israel from Gaza since July 8, and the Israeli military has uncovered more than 30 tunnels.
