Gaza health officials say the death toll from an Israeli strike on a compound housing a UN 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; al-Jazeera puts that number at 200. Sources tell al-Jazeera the number killed could be as high as 30.
Today's strike is the fourth time a UN facility has been hit in fighting between Israel and Palestinian militants in Gaza, but it's the first time casualties have been reported. (Read more Israel stories.)
