Twitter Hackers Announce 'World War III'

One tweet posted under the UPI account quoted Pope Francis as saying, "World War III has begun."

Another message delivered on the Post account said the USS George Washington, an aircraft carrier, was "engaged in active combat" against Chinese warships in the South China Sea.

The tweets were subsequently deleted.

A tweet from the News Corp-owned Post later noted that "Our Twitter account was briefly hacked and we are investigating."

The fake tweets were not just about war. One posted on UPI said "Just in: Bank of America CEO calls for calm: Savings accounts will not be affected by federal reserve decision."

UPI later acknowledged it was hacked, and said in a dispatch that "six fake headlines were posted in about 10 minutes."

On Twitter, UPI noted that "World War III has not started, thankfully."

Several media organizations have had their Twitter feeds hacked over the past two years including Agence France-Presse and the BBC. Also this week the Twitter feed for the Pentagon's Central Command was taken over by a group supporting the Islamic State jihadists.

A Pentagon official said the tweet about hostilities with China was "not true."
