Leader's top military advisor, Major General Hassan Firouzabadi, said the self-styled Islamic State militant group further blackened its name among Muslims by conducting terror operations in the holy city of Medina. "By this act, it was proved that IS is the enemy of Islam's Prophet (PBUH) too and it is a clear sign by which we can explicitly see the hands of Israel and other enemies of Islam in using IS," he said. A blast claimed by IS rocked Prophet Muhammad's [PBUH] mosque when a suicide bomber blew himself up in Medina on Monday, Fars News Agency reported.
