'Did They Shoot?' Video Captures Moment of Museum Attack

Riveting new video has emerged capturing the moment a group of tourists in Tunisia realized the museum they were in had come under militant attack . Visitors jump and look around when the first loud bang interrupts a guided tour of the Bardo museum in Tunisia's capital Tunis. The video was taken by Maria Rita Gelotti and released by The Associated Press on Tuesday. Gelotti and her husband Marcello Salvatori escaped the March 18 attack by two Tunisian men that killed 20 tourists, including Japanese, Polish, Italian and Spanish nationals.
