Israel says the site was used by Hamas for planning terrorist attacks.
An Israeli airstrike on a school housing displaced people sheltering in the central Gaza Strip reportedly killed at least 17 people on Thursday, nearly all women and children, according to Palestinian medical officials.
A further 42 people were wounded in the attack, says the Awda Hospital, which received the casualties. Thirteen children were among the dead,according to the hospital’s records.
Israel said it had targeted a Hamas command centre at the site "used by the terrorists to plan and execute terrorist attacks".
The IDF has carried out strikes on similar sites in recent months, saying it targets militants and their infrastructure.
The strike came as US Secretary of State Antony Blinken said Israel had achieved its target of effectively dismantling Hamas and that negotiations over a cease-fire would resume in the coming days.
Speaking to reporters in Qatar, Blinken said negotiators from both sides would return to Doha to renew talks.
“What we really have to determine is whether Hamas is prepared to engage,” Blinken said on his 11th visit to the region since the start of the war.
Hamas’ political representatives have not so far signalled a softer stance.
