Update as of 3:20 a.m. EST: Seven people have been arrested in connection with the attack on the Charlie Hebdo office in Paris, the French interior ministry said on Thursday, according to media reports. Although details of those arrested have not been released, they are all believed to be either friends or associates of the three suspects, two of whom have still not been found, according to a report by The Telegraph.

Update as of 10:50 p.m.: The New York Times confirmed that the youngest of the three suspects, Hamyd Mourad, surrendered. According to the Times, the 18-year-old walked into a police station in the French town of Charleville-Mézières and gave himself up. The two other suspects remain at large, the Times wrote, citing a spokeswoman for the Paris prosecutor. The report, also confirmed by the AP, contradicts an earlier NBC report that one of the suspects had been killed.

Updated as of 9:05 p.m.: Both AFP and France 24 are reporting that the youngest of the three suspects in the Paris shooting has turned himself in to authorities. NBC’s report that one of the suspects is dead has yet to be confirmed.

Original Story:

An anti-terror raid thought to be connected to the attack on the French weekly Charlie Hebdo was carried out late Wednesday in Reims, in northeastern France. The French news agency Agence France-Press reported the situation on Twitter, citing police sources.

The raid was reportedly carried out by France’s elite anti-terrorist unit. AFP quoted one of the officials as vowing, “There will be a showdown.”

According to anonymous senior U.S. officials cited by NBC News, one suspect in the shooting was killed and two others are in custody.

Earlier Wednesday, French officials identified brothers Said Kouachi, Cherif Kouachi and Hamyd Mourad as suspects in the terrorist attack that left 12 people dead and another 11 wounded. Wearing black masks and armed with AK-47s, the men reportedly shouted “Allahu Akbar” (“God is great”) as they fired on staffers of the satirical magazine, known for publishing cartoons mocking the Prophet Muhammad.
