Updated: Latest on the manhunt for Paris attack mastermind

The global hunt for the alleged mastermind of the Paris attacks is heating up. Across Belgium and France, hundreds of homes are being raided by armed police looking for the Islamic State leader Abdelhamid Abaaoud.

Abaaoud is a zealot so devoted to the cause of holy war that he recruited his 13-year-old brother to join him in Syria.

The child of Moroccan immigrants who grew up in the Belgian capital’s scruffy and multiethnic Molenbeek-Saint-Jean neighborhood, the fugitive, in his late 20s, was identified by French authorities on Monday as the presumed mastermind of the attacks last Friday in Paris that killed 129 people and injured hundreds.

What’s more, one French official told that Abaaoud is believed to have links to earlier terror attacks that were thwarted: one against a Paris-bound high-speed train that was foiled by three young Americans in August, and the other against a church in the French capital’s suburbs.

“All my life, I have seen the blood of Muslims flow,” Abaaoud said in a video made public in 2014. “I pray that Allah will break the backs of those who oppose him, his soldiers and his admirers, and that he will exterminate them.”

Belgian authorities suspect him of also helping organize and finance a terror cell in the eastern city of Verviers that was broken up in an armed police raid on Jan. 15, in which two of his presumed accomplices were killed.

The following month, Abaaoud was quoted by the Islamic State group’s English-language magazine, Dabiq, as saying that he had secretly returned to Belgium to lead the terror cell and then escaped to Syria in the aftermath of the raid despite having his picture broadcast across the news.

“I was even stopped by an officer who contemplated me so as to compare me to the picture, but he let me go, as he did not see the resemblance!” Abaaoud boasted.

There was no official comment from the Belgian federal prosecutor’s office about Abaaoud’s reported role in the Paris attacks, but Belgian police over the weekend announced the arrest of three suspects in Molenbeek, his old neighborhood, and were carrying out numerous searches there Monday.

The hardscrabble area in the west of Brussels has long been considered a focal point of Islamic radicalism and recruitment of foreign fighters to go to Iraq and Syria.

Abaaoud’s image became even grimmer after independent journalists Etienne Huver and Guillaume Lhotellier, visiting the Turkish-Syrian frontier, obtained photos and video last year of Abaaoud’s exploits across Syria. The material included footage of him and his friends loading a pickup truck and a makeshift trailer with a mound of bloodied corpses.

Before driving off, a grinning Abaaoud tells the camera: “Before we towed jet skis, motorcycles, quad bikes, big trailers filled with gifts for vacation in Morocco. Now, thank God, following God’s path, we’re towing apostates, infidels who are fighting us.”
