NBC News reports: One of the suspects in the Paris attack on Charlie Hebdo magazine has been killed and the two others are in custody, two senior U.S. counterterrorism officials told NBC News on Wednesday.

Mashable: French police officials have identified three men as suspects in the deadly terror attack at the Paris offices of the Charlie Hebdo newspaper.

One of the men, 35-year-old Cheriff Kouachi, was convicted on terrorism charges in 2008.

Two of the suspects, brothers Cheriff and Said Kouachi, 32, are French nationals who were born to Algerian parents in Paris. The nationality of a third man, Hamid Mourad, 18, is unknown; police believe he is a high school student.

Their names circulated on Facebook and Twitter for an hour before French authorities confirmed that the Kouachi brothers had been identified.

One of the officials who spoke to the Associated Press said they were linked to a Yemeni terrorist network.
