Seen in these first videos from inside, recorded by one of the hostages and broadcast today by algerian state tv. Based on official accounts, at least 38 of these men were either executed or killed in the bloody rescue attempts. Among the dead, three americans, gordon lee rowan and fred buttaccio. We asked him, do you feel safe? You don't have to go. And he said, oh, nothing's happened there in so long. Reporter: The wife of one of the seven americans to survive told abc news her husband hid at the gas plan for 2 1/2 days, often just feet away from the terrorists.
