The YouTube and Twitter handles of the United States Central Command (Centcom) have been hacked by a group that claims to belong to the Islamic State (IS) as the accounts were suspended for a few hours.
According to BBC, a message on Centcoms's Twitter feed addressed American soldiers saying they were "coming". The message was signed by the Islamic State.
There were some internal military documents that appeared in the Centcom Twitter feed as well.
Centcom said that the issue was "cyber vandalism" but not a serious data breach.
The Central Command also said that they were viewing the incident purely as a case of "cyber vandalism".
Meanwhile, U.S. President Barack Obama had been giving a speech on cyber security reflecting on the recent Sony Pictures cyber attack.
