The Islamic State jihadist group has urged Muslims to carry out new attacks after the targeting of France's Charlie Hebdo magazine.
Abu Mohamed al-Adnani, referring to attacks in France, Australia, Canada and Belgium, urged "Muslims in Europe and the infidel West to attack the Crusaders where they are".
"We promise that in the Christian bastions they will continue to live in a state of alert, of terror, of fear and insecurity... You have seen nothing yet," a recording by the group's spokesman said.
He added that the group would consider as "enemies" those Muslims who were able to carry out such attacks but failed to do so.
The threat is just the latest instance in which the jihadist group has urged Muslims to carry out attacks in the West.

It also made reference to attacks last year in Australia, Canada and Belgium.
Western intelligence agencies have regularly raised the alarm about the possibility that Western sympathisers of IS and other jihadist groups could carry out attacks in the West.
Their concerns have been heightened by the thousands of Western recruits who have flocked to Syria and Iraq to fight alongside jihadist groups.
