A timeline of the Charlie Hebdo terror attack

Wednesday morning

About 11:30 a.m. Wednesday, according to the French newspaper Le Monde, gunmen dressed in black and wearing bulletproof vests forced their way into a building two doors down from Charlie Hebdo, asking where to find the magazine.

They then headed to the correct building, where they killed an officer on security detail, officials say. They later encountered a Charlie Hebdo cartoonist who was on her way out of the building and demanded she lead them to the offices. Once there, she is told to enter a security code to open its fortified door, according to the newspaper.

The gunmen barged in during a lunchtime editorial meeting, separating men and women and calling out the names of employees they intended to kill, according to said Dr. Gerald Kierzek, a physician who treated wounded patients and spoke with survivors.

He described the gunfire as a precision execution.

The gunmen said they were avenging the Prophet Mohammed and shouted “Allahu akbar,” which translates to “God is great,” Paris Prosecutor Francois Molins said.

In the supermarket standoff, suspected hostage-taker, Amedy Coulibaly, was killed in the operation and some police officers were injured, Disant said. Four hostages were killed and 15 survived, according to Israeli government sources who characterized a phone conversation between Israeli Prime Minister Benjamin Netanyahu and French President François Hollande.

Coulibaly’s suspected accomplice — 26-year-old Hayat Boumeddiene — escaped as hostages ran from the store, Disant said.

Authorities search the country for Boumeddiene.

Al Qaeda in the Arabian Peninsula claimed responsibility for orchestrating the attack on Charlie Hebdo, the founder of the magazine The Intercept, Jeremy Scahill, told CNN. CNN has not independently confirmed this claim.
