Update, 10:25 am ET: The Washington Post has created a detailed map of the locations of the two hostage situations on the outskirts of Paris. The Kouachi brothers, believed by authorities to be part of the three-man team who killed 12 people in a shooting assault on satirical magazine Charlie Hebdo on Wednesday, are holed up with hostages in a printing house near Charles De Gaulle Airport in the town of Dammartin-en-Goelle; the second hostage situation, at a kosher grocery store in the Porte de Vincennes neighborhood in Paris, is believed to be orchestrated by Amedy Coulibaly and Hayet Boumddiene, who are allegedly responsible for the fatal shooting of a French policewoman on Thursday.
Update, 9:39 am ET: Police have ordered the closure of all shops along the Rue des Rosiers in Le Marais, a predominantly Jewish neighborhood in central Paris far from the locations of both hostage situations but only a kilometer (0.6 miles) away from Charlie Hebdo's offices, according to the Associated Press. Le Marais, a major center of the Parisian Jewish community since the late 19th century, is home to many art galleries, fashion houses and approximately 40% of Paris' LGBT-oriented businesses. On a Friday afternoon, mere hours before the Jewish Sabbath, the Rue des Rosiers would typically be crowded with shoppers.

Paris police released a photo of Amedy Coulibaly as a suspect in the killing Thursday of a policewoman, and the official named him as the man holed up in the market. A second suspect, a woman named Hayet Boumddiene, is the gunman's accomplice.
A police source previously told Reuters that the gunman are connected to the same jihadi terror cell as the suspects in the Charlie Hebdo massacre.
Another official told the AP that Coulibaly opened fire in the market Friday and declared "you know who I am."
Boumeddiene, who has just been named by the police as a suspect in the killing of a policewoman on Thursday, is the former partner of Coulibaly, according to Le Monde.

Original story: The new hostage crisis comes as the two brothers suspected in a newspaper terror attack were cornered inside a printing house northeast of Paris on Friday, taking a hostage and telling police they "want to die as martyrs," a French lawmaker told the Associated Press.
Earlier, police had chased a vehicle at high speed along a main road heading towards Paris as one of France's biggest security operations in recent times unfolded. Reuters reports that gunshots rang out and the suspects abandoned their car in Dammartin-en-Goele, a small town of about 8,000 residents near Charles de Gaulle airport.
French anti-terrorist police have sealed off the town in an effort to corner and apprehend the two suspects.
Police trucks, ambulances and armored vehicles descended on the area close to Paris's Charles de Gaulle airport after the suspects took refuge with at least one hostage in a building on an industrial estate, according to police sources.
Authorities evacuated a nearby school around midday Friday after the suspects agreed by phone to allow the children safe passage, town hall spokeswoman Audrey Taupenas told the Associated Press.
"They said they want to die as martyrs," Yves Albarello, a local lawmaker who said he was inside the command post, told French television station i-Tele.
The two suspects have been on the run since they stormed the Paris offices of the Charlie Hebdo weekly newspaper on Wednesday, killing ten journalists and two police officers in an attack that raised security fears across the world. The paper was known for its irreverent satirical treatment of Islam as well as other religions and political leaders.
The two suspects, Said and Cherif Kouachi, are French citizens of Algerian-origin resident in Paris. French media say Cherif, 32, was convicted of terrorism charges in 2008, and a U.S. official said both brothers were on the American no-fly list. A senior Yemeni intelligence source told Reuters one of the two was in Yemen for several months in 2011 for religious studies.
