Belgian police on Tuesday were hunting for a 15-year-old boy seen on a recent video calling for “the murder of all Christians.”

Footage published on a French website reveals the unnamed teenager speaking in Arabic, proclaiming, “Oh Allah, destroy the odious Christians. Oh Allah Kill them all,” The Telegraph reported.

The teenager, who is the son of a radical imam, is also quoted as stating, “Don’t spare any of them,” in reference to the annihilation of Christians. 

The video, recorded in Verviers, has city government officials on high alert. Mayor Muriel Targnion ordered police to uncover the boy’s whereabouts “as a matter of urgency,” according to reports.

Police have identified the boy and have confirmed he was on a list of radicalized individuals, but withheld his name, The Telegraph added.

A Belgian newspaper claims the boy’s father is an Islamist leader named El Alami Amaouch. Belgian law enforcement officers reportedly have sought to deport the imam to the Netherlands.

Belgium’s Minister for Asylum and Migration, Theo Francken, called Amaouch the "spiritual father” of a group of terrorists in Verviers. Describing the teenage son's video, Francken said, “It seems that it runs in the family.”

Verviers was the site of a January 2015 anti-terror raid that resulted in more than a dozen arrests. Investigators say Abdelhamid Abaaoud, the suspected ringleader of the November 2015 massacre in Paris, may have previously directed a terror cell based in Verviers.

Officials have made previous attempts to deport Amaouch but have faced delays from his appeals, Francken added.
