Palestinian officials say an Israeli air strike has killed 10 people in the Gaza Strip, including three children and two high-ranking officers in the Hamas-run police force.

The strike early on Thursday hit a tent in an Israeli-declared humanitarian zone known as Muwasi, where hundreds of thousands of displaced people are sheltering in tents during the cold and rainy winter.
