PARIS  — The Belgian jihadi suspected of masterminding deadly attacks in Paris was killed in a police raid on a suburban apartment building, the city prosecutor’s office announced Thursday.

Paris Prosecutor Francois Molins’ office said 27-year-old Abdelhamid Abaaoud was identified based on skin samples. His body was found in the apartment building targeted in the chaotic and bloody raid in the Paris suburb of Saint-Denis on Wednesday.

Police launched the operation after receiving information from tapped phone calls, surveillance and tipoffs suggesting that Abaaoud was holed up there.

Killed along with Abaaoud was a woman who blew herself up with an explosives vest at the beginning of the raid. Eight people were arrested.

With France still reeling from the Friday attacks that killed 129 people and wounded hundreds of others, Prime Minister Manuel Valls warned that Islamic extremists might at some point use chemical or biological weapons, and urged lawmakers to extend a national state of emergency by three months.
