Charlie Hebdo suspects killed; 4 hostages die in second standoff

At least four hostages were killed in a standoff at an east Paris supermarket Friday, according to multiple news outlets. The gunman also was suspected in the shooting death of a policewoman Thursday. 

Reuters and Agence France-Presse reported five total dead in the incident, including the suspect, identified as Amedy Coulibaly. Police are still looking for his accomplice, Hayat Boumedine, who authorities believe escaped during the confusion. Boumedine may be Coulibaly's wife or girlfriend and is believed to have been involved in the murder of a female police officer on Thursday.

However, 16 hostages were freed. The incident is related to the massacre of at the Charlie Hebdo office where 12 people were killed Wednesday.

The Kouachi brothers, suspected of the massacre at the magazine, have been killed following another hostage standoff Friday, police officials said. Police began the raids simultaneously. 

Al-Qaida in Yemen has claimed responsibility for France's deadliest terror attack in decades, saying they directed the attack against the satirical publication. 

The brothers and Coulibaly have engaged in terrorist activities; all were French-bo citizens who became Islamic radicals and trained abroad only to retu home and carry out attacks.

Coulibaly contacted a French television station, saying he and the brothers were in contact, coordinating their actions. 

French President Francois Hollande called the attack at the Jewish market \"anti-semitic.\" He also called for all of France to represent the values of democracy Sunday, when a unity rally is planned in Paris. 

\"We are a free people,\" Hollande said. \"We do not yield to pressure. We are not afraid.\"

The Associated Press stated Cherif and Said Kouachi were killed and their lone hostage had been freed after several hours inside a printing house in Dammartin-en-Goele, a town close to Charles de Gaulle Airport. The AFP said they were killed after they opened fire on security forces.

The AFP also posted a photo to Twitter showing officers recovering hostages at the east Paris supermarket.  

Flash-bang grenades and gunfire could be heard at the scene of both hostage situations. Police launched simultaneous assaults at the two sites roughly 20 miles apart. 

Earlier, the man police believed was Coulibaly called a television station and threatened to kill hostages if police did not allow the Hebdo attack suspects to be released from their standoff with authorities, an unnamed official told the Associated Press. 

The perpetrator said to people inside the supermarket, \"You know who I am,\" the official told the AP. That standoff began shortly after the situation just outside Paris with Cherif and Said Kouachi.

French authorities made contact with the brothers during hostage negotiations. They said they want to \"die as martyrs,\" the officials said.

The town and a school were placed on lockdown, and runways were closed at one point at the airport, CNN reported.

The gunmen stormed into the offices of the satirical newspaper Charlie Hebdo on Wednesday, setting off a manhunt involving thousands of French officials. Eleven more people were wounded in the assault that captured the attention of the world.

Among the victims was a policeman who was a Muslim. He was shot execution style while laying on the ground with his hands up.

During the search for the Kouachi brothers, the two robbed a gas station and stole a car from a woman.

Cherif Kouachi, 32, was sentenced to three years in prison in 2008 for recruiting for militant movements in Iraq, but Bloomberg has reported that half the sentence was suspended and the rest was spent in pretrial detention.

Said Kouachi, 34, also was known to French authorities. U.S. security officials said the French believe he received weapons training in Yemen in 2011. A Yemeni official told the AP on Friday that Said Kouachi was suspected of fighting for al-Qaida in the country. 

Both brothers are French citizens. CNN affiliate BFMTV reported that Said left an ID at the scene of the attack.  

Both men were on the U.S. no-fly list, the Associated Press reported.
