Israeli air strikes on al-Bureij refugee camp and Jabalia town in central and northern Gaza killed at least 17 Palestinians on Wednesday, the official Palestinian news agency WAFA reported.The Israeli military had no immediate comment although in a post on X, its Arabic spokesperson warned residents of al-Bureij earlier to evacuate ahead of an imminent strike against fighters firing rockets from the area.The instruction to clear the al-Bureij camp has caused a new wave of displacement, although it was not immediately clear how many people were affected.Palestinian and United Nations officials say no place is safe in Gaza and that evacuations worsen the humanitarian conditions of the population.According to the Palestinian civil defence, more than 1,500 tents sheltering displaced people across Gaza were flooded by heavy rains over the past two days, leaving people exposed to the cold, their belongings damaged.Hundreds more tents experienced less severe flooding that still left displaced people unable to use them.Much of the area around the northern towns of Beit Hanoun, Jabalia and Beit Lahiya has been cleared of people and razed, fuelling speculation Israel intends to keep the area as a closed buffer zone after the fighting in Gaza ends.WAFA said the military blew up residential blocks in Beit Lahiya and in and around Jabalia, while tanks shelled parts of Gaza City and the al-Bureij camp.45,553 Palestinians killed and 108,379 injured Israel's military offensive on Gaza since October 7, 2023, Gaza Health Ministry said Wednesday.
