Group tells AFP news agency it cannot be defeated with the killing of its leaders

At least 28 people have been killed in an Israeli airstrike on a school turned shelter in the Jabaliya neighbourhood of Gaza City, amid accusations Israel intends to forcibly expel the remaining population in a renewed ground campaign.

The bombing of Abu Hussein school in Jabaliya on Thursday killed 28, including doctors and several children, and injured dozens more, according to health officials, who warned the final toll was likely to be higher. Another 11 people were killed in two separate airstrikes in Gaza City, and it was unclear how many were killed in other strikes in central and southern Gaza.
