Two brothers suspected in Wednesday’s attack on the French satirical newspaper Charlie Hebdo were killed when police stormed their hideout in northern France on Friday.

A second, separate siege at a Jewish supermarket in Paris ended the same day with the death of one gunman and four hostages.

A hostage taken by the brothers in a print shop in Dammartin-en-Goele, a town northeast of Paris, was recovered safely.

The two were wanted for a bloody attack on the Paris offices of Charlie Hebdo in which twelve people, including cartoonists and editors of the magazine as well as two police officers, were killed.

French authorities had mobilized a force of nearly 90,000 in search of the attackers.

Video of Wednesday’s attack recorded one of the gunman praising Allah and crying, “We have killed Charlie Hebdo. We have avenged the Prophet Muhammad.”

The magazine is known for lampooning Islam and had previously been threatened by religious extremists.

Most Muslims consider making an image of Muhammad to be blasphemous.

Before his death, one of the brothers phoned in to BFM-TV, claiming he had received financing from an Al Qaeda preacher in Yemen.

“I was sent, me, Cherif Kouachi, by Al Qaeda of Yemen,” he said. “I went over there and it was Anwar al-Awlaki who financed me.”

Awlaki was a known Al Qaeda recruiter. He was killed in an American drone strike in September 2011.

The gunman at the Paris supermarket also called BFM-TV before he died, claiming allegiance to the Islamic State. The assailant, who was identified as Amedy Coulibaly, a Frenchman of Senegalese descent, said he had jointly planned the attacks with the Kouachi brothers.

Police had been hunting Coulibaly and a female accomplice after a police officer was killed on Thursday. The woman remained at large.

France was already on high terror alert before the attacks. Islamic militants had urged attacks on the country in reprisal for its involvement in military operations against Islamists in Africa and the Middle East.

French forces are participating in strikes against Islamic State militants in Iraq and carrying out counterinsurgency operations across French-speaking West Africa.
