IS announces leader's death and names replacement

The jihadist group Islamic State (IS) has announced the death of its leader, Abu al-Hassan al-Hashemi al-Qurayshi.

An audio message from the group’s spokesman said he was killed while fighting what he called “the enemies of God”, but he gave no further details.

He became leader in March, after his predecessor blew himself up during a raid by US forces in north-east Syria.
