President Francois Hollande says France is "waging war" against terrorism and will not back down from international military operations against Islamic extremists despite recent deadly attacks.

Hollande said "it is not a war against religion, it's a war against hate." He spoke to leading diplomats Friday as French authorities are on alert for new terrorist attacks. They are hunting for accomplices of three men claiming links to al-Qaida and the Islamic State group who killed 17 people last week, before being killed by police.

He said France remains determined to continue its anti-terrorist operations in Iraq and northern Africa despite repeated threats of retaliation, saying "We are not afraid."

Hollande urged Europe to take tougher joint measures against terrorism.
