At least 50 people were killed and over many injured in a fire likely caused by an oxygen tank explosion at a coronavirus hospital in Iraq's southern city of Nassiriya, health officials and police said. As rescuers combed the smoke-charred building in search of more bodies, Prime Minister Mustafa al-Kadhimi held urgent meetings with senior ministers and ordered the suspension and arrest of health and civil defense managers in Nassiriya, his office said in a statement.
