The Orlando gunman who killed 49 people at a gay club wrote a series of Facebook posts before and during the attack raging against the 'filthy ways of the west'. Omar Mateen blamed US airstrikes for the death of 'innocent women and children', writing 'now taste the Islamic state of vengeance' on the same morning he fired shots into Pulse nightclub.
Mateen's final post was a warning: 'In the next few days you will see attacks from the Islamic state in the usa'.
The Facebook posts were revealed in a letter sent by the Senate Homeland Security Committee to Facebook CEO Mark Zuckerberg that requested additional information on Mateen's online activity, Daily Mail reports.
'I'm the shooter. It's me. I am the shooter,' the caller told the network's stunned Matthew Gentili.
Mateen then announced that he was carrying out the atrocity in the name of ISIS.
'He did it for ISIS, and he started speaking Arabic,' Gentili said. 'At the time, I didn't know what he was saying. He was speaking so fast. But it was...he was speaking fluently.'
