In a speech on Sunday, Jordan’s King Abdullah II, denounced extremism, saying that it is “the greatest threat to our region” and called upon Muslims to lead the fight against it.

The speech did not specifically reference the attacks in Paris that killed 129 people, but King Abdullah has condemned them as a “cowardly terrorist act” in previous speeches.

King Abdullah claimed that confronting extremism is “both a regional and international responsibility, but it is mainly our battle, us Muslims, against this who seek to hijack our societies and generations with intolerance takfiri ideology.”

“Takfiri” refers to the radical Islamic practice of declaring one’s enemies to be infidels worthy of death.

Jordan is part of the US-led coalition and has launched airstrikes against Daesh, which has claimed responsibility for the attacks.
