Every country potential target of terrorism – Hollande

France has been tightening security after a spate of attacks by Islamist terrorists claimed hundreds of lives in less than a year.

A series of nearly simultaneous bomb and gun attacks in Paris in November 2015 killed 130 people, while a truck attack in Nice on the Bastille Day in July left 86 people dead and prompted France to extend the state of emergency for six months.

"Every country is potentially a terrorist target these days," Hollande said. "That is why I expect that the United Nations also takes on its responsibilities."
