Don't lower guard on IS, Macron warns

French President Emmanuel Macron has renewed his warning about the Islamic State group as he attended a summit on Iraq that has been overshadowed by recent events in Afghanistan.

Macron told Iraq's PM in Baghdad: "We all know that we must not lower our guard, because (IS) remains a threat, and I know that the fight against these terrorist groups is a priority of your government."

Iraq has long suffered attacks by jihadists militants.

The Afghan branch of IS said it was behind the bomb attack on Kabul airport on Thursday that killed as many as 170 people.
