The Israeli military said it had been targeting a loaded weapons launcher in the area, where thousands of displaced people are sheltering in a tent camp.
The Israeli military has bombed a densely populated tent encampment in southern Gaza designated as a humanitarian zone for thousands of displaced Palestinians, saying the airstrike targeted a loaded weapons launcher in the area.
The Palestinian news agency Wafa and a paramedic based at a medical center where the wounded were taken said that at least one person had been killed in the airstrike on the zone, called Al-Mawasi, which took place on Wednesday. Wafa reported that the victim was a child and that more than 20 other people had been injured.
The Israeli military said that it had targeted the launcher because it posed a threat to Israeli civilians but did not give further details or say what type of weapons the launcher was carrying. The military added that it had issued advanced warnings to civilians in the area to evacuate.
The Israeli military has carried out a number of strikes on Al-Mawasi in the past and has accused Hamas, the armed Palestinian group that led the Oct. 7, 2023, attack on Israel, of systematically using the humanitarian zone and civilian infrastructure to attack Israelis.
Video on social media, verified by The New York Times, captured a projectile and a large explosion. The projectile hits the ground with a deafening boom, and people can be seen running away as a cloud of dust flies into the sky.
Other video from the scene captured the aftermath of the explosion, showing a large crater and damage to a number of tents.
The international aid group Doctors Without Borders said that one of its clinics, which was about 250 yards from where the strike hit, was also damaged and medical equipment destroyed.
Gabriella Bianchi, a spokeswoman for Doctors Without Borders, said that the aid group had not received any direct warning that a blast was imminent. Residents who received alerts on their phones from the Israeli military did inform the staff, Ms. Bianchi said, but that left only a few minutes to evacuate personnel and hundreds of patients.
In a statement on social media, Doctors Without Borders condemned the attack, saying, “The use of heavy weapons in zones declared by Israeli authorities as safe, is further proof of the blatant disregard for Palestinian lives and humanitarian law.”
