Israeli air strikes killed at least 18 people in the Gaza Strip on Thursday, including three children and two high-ranking officers in the Hamas-run police force, according to Palestinian and hospital officials.

One 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.
