The incident occurred during routine water delivery at the Mansoura water filling point, a key facility supplying Gaza City, UNICEF said in a statement, adding that two other individuals were injured in the attack.The agency said it was “outraged” by the killings and stressed that humanitarian personnel, civilians and essential infrastructure must be protected under international humanitarian law.

It urged Israeli authorities to investigate the circumstances surrounding the incident.Israel’s embassy in Washington did not immediately respond to requests for comment.The development comes amid a fragile ceasefire between Israel and Hamas that has been in place since October, ending two years of full-scale conflict.

Despite the truce, Israeli forces remain deployed across a large depopulated zone covering more than half of the Gaza Strip, while Hamas continues to control the remaining coastal territory.Violence has persisted since the ceasefire, with local medics reporting more than 750 Palestinian deaths, while militants have killed four Israeli soldiers.

Both sides have accused each other of violating the terms of the truce.UNICEF said the suspension of activities at the water site could further affect access to clean water for civilians in Gaza, where humanitarian conditions remain severe.
