An Israeli attack on a school used to house displaced Palestinians has killed at least 15 people in central Gaza, officials say.
The Hamas-led Gaza Civil Protection Agency said the Nuseirat camp site was hit by a volley of artillery on Sunday, killing entire families and wounding dozens of others.
The Israeli Defense Forces (IDF) said it is investigating the reports.
Earlier, five children were reportedly killed by a drone strike while playing on a street corner in northern Gaza.
A civil defense spokesman said at least 50 people were injured and more than a dozen were killed in the attack on al-Mufti school, where hundreds of displaced people from across the Gaza Strip were sheltering.
The main areas of conflict in Gaza in recent days have been in the north, where Israeli forces have been intensifying attacks for more than a week as part of a major ground operation. Hundreds have been killed since then, Gazan authorities say.
Residents of Beit Hanoun, Jabalia and Beit Lahiya have reported being cut off from nearby Gaza City, while Israeli tanks have been seen on the outskirts of the territory’s largest city.
Hospitals in the area are running low on supplies, although the World Health Organization said a joint operation with the Red Cross had resupplied two of them – after nine days of attempts.
The five children in northern Gaza were reportedly killed in an Israeli airstrike while playing on a street corner in the Al-Shati camp.
Graphic images of the scene in the aftermath show the bloodied bodies of what appeared to be young teenage boys.
One of them appeared to be holding a number of glass marbles.
According to a report from the scene told to a BBC correspondent, a drone strike hit a person walking on the street, killing the children and injuring seven other people.
Later images showed the bodies of the five boys wrapped in white shrouds and laid side by side on the ground.
An aunt of one of the boys, named Rami, wrote a moving tribute to him on social media. She said the family moved to Al-Shati after the war forced them to leave their homes in Jabalia for a “safer area.”
The IDF has not yet responded to questions about the incident.
During the past year of war, the Hamas-led Health Ministry has reported that more than 42,000 people have been killed.
About 1.9 million of Gaza’s 2.4 million residents have been displaced by the war. Many of them have been forced to move several times to escape.
The fighting began after Hamas launched an unprecedented attack on northern Israel on October 7 last year, killing around 1,200 people in northern Israel and taking more than 200 hostage in Gaza.
