Turkish President Recep Tayyip Erdogan has announced his country's security forces have killed a suspected key leader of Islamic State (IS) in Syria.

The leader has been identified as  Abu Hussein al-Qurayshi.

Erdogan told broadcaster TRT Turk the IS leader was "neutralised" in a Turkish MIT intelligence agency operation on Saturday, reports BBC.

The ISIS terror group did not comment on the issue so far.

The MIT intelligence agency had been following Qurayshi for a "long time", Erdogan was quoted as saying by BBC.

"We will continue our struggle with terrorist organisations without any discrimination," he added, providing no further details.
