At least 43 people have been killed in Israeli strikes across the Strip since dawn on Thursday. That includes at least 18 people killed in an attack on a school-turned-shelter in Al Nuseirat in central Gaza, where hundreds of Palestinians had taken refuge. Another strike in neighbouring Al Maghazi shortly afterwards killed and injured several more people. Al Jazeera’s Hani Mahmoud reports from Deir Al Balah in Central Gaza. Just a warning—there are distressing images in his report.
