CNN reports: French radio reporter Julien Pearce was inside the Bataclan theater when gunmen entered. Click here for his firsthand account. He said Two men dressed in black started shooting what he described as AK-47s, and after wounded people fell to the floor, the two gunmen shot them again, execution-style, he said. The two men didn't wear masks and didn't say anything. The gunfire lasted 10 to 15 minutes, sending the crowd inside the small concert hall into a screaming panic, said Pearce, who escaped. He said he saw 20 to 25 bodies lying on the floor. The hostage situation at the Bataclan continued early Saturday.
