At least 42 people were killed during the attack on supporters of Mursi outside an elite army base in Cairo, a senior medical official said. \"The death toll is 42 dead and 322 wounded,\" Ahmed al-Ansari, the deputy head of emergency services, told AFP. The Muslim Brotherhood, which has led pro-Mursi demonstrations, said 35 of its supporters were killed when police and troops fired at them while they were praying at dawn. Witnesses, including Brotherhood supporters at the scene, said the army fired only tear gas and warning shots and that \"thugs\" in civilian clothes had carried out the deadly shooting.
