At least 21 people, including five children and two women, were killed in strikes in central Gaza on Monday night, according to Al-Aqsa Martyrs hospital, where the bodies were taken.
The strikes took place on the anniversary of the Oct. 7 attack in southern Israel that triggered the war between Israel and Hamas.
Two strikes hit houses in the Bureij refugee camp. An Associated Press journalist counted the bodies along with about a dozen wounded, including several children.
Emergency responders said more people are thought to be under the rubble.
The Palestinian death toll in the war in Gaza is nearing 42,000, according to Gaza’s Health Ministry, which doesn't differentiate between civilians and fighters.
