Israeli air strikes have destroyed another tower block in Gaza after reportedly warning occupants to leave so the armed forces could target alleged Palestinian militants amid their ongoing conflict with Hamas.The ten-storey Al-Shourouk high-rise building was levelled to the ground on Wednesday after being struck by missiles fired by the Israel Defense Forces (IDF).Footage of the final moments of collapse showed the tower block, which housed a number of media offices, fall to the ground and send a large column of smoke and debris into the air.
