At least 28 people were killed in an Israeli strike on a former school building in the Gaza Strip on Thursday, Palestinian medical officials said.
The attack on the central city of Deir al-Balah also left dozens of people injured, the Hamas-controlled Health Ministry in the sealed-off coastal territory said.
The building was being used to accommodate Gazans who have been internally displaced by the year-old war between Israel and Hamas militants.
Israel’s military said it attacked a Hamas command centre that was located in the building and that measures were taken to reduce the risk to civilians.
The information provided by both sides could not be independently verified.
The Gaza war was triggered by the unprecedented terrorist attack on southern Israel by Hamas and its allies just over a year ago. Members of the militia and other gunmen killed over 1,200 people and abducted around 250 more into the Gaza Strip.
Since then, Israel has been waging a war in an attempt to destroy Hamas both as a military formation and political organization.
The number of Palestinians killed since the beginning of the war has risen to over 42,000, according to the health authorities in Gaza.
