Turkey said on Monday Islamic State (IS) jihadists must be totally pushed out of the Syrian border region, after a weekend suicide bombing in the city of Gaziantep blamed on the group left at least 54 dead.

"Our border must be completely cleansed from Daesh," Foreign Minister Mevlut Cavusoglu said in televised remarks, using an Arabic acronym for the IS group. "It is our most natural right to fight at home and abroad against such a terrorist organisation."
