A spokesman of Iran's highest religious leader Ayatollah al-Khamenei said that Islamic State (IS) leader Abu Bakr al-Baghdadi was surely killed in a extremist group.

Iran's state news agency IRNA reported on Thursday.The leader of the Revolutionary Guard of Iran, Quds Bahini, told al-Shiraji, "Terrorist Baghdadi has been killed safely''.Bagdadi had announced the caliphate in 2014 in the Grand Mosque of Mosul, Iraq. After this news has been published many times about his death. But none of this has proved to be true. Earlier this month, the Russian Defense Ministry claimed Baghdadi was killed in the air strike. The deadliest leader of the IS was also claimed to have been killed in the attack. On Thursday, Iraqi forces claimed that they had restored the Grand Nauri mosque in Mosul, the place to declare the Khilafah of IS. But they did not tell anything about Baghdadi.
