American Jihadi called for attack in Texas

An American jihadi allegedly called for Charlie Hebdo-style attack at a Texas 'draw Muhammad' event more than a week before it was attacked by two gunmen.

Mohamed Abdullahi Hassan, a 25-year-old fighter with the Al Shabaab terrorist group in Somalia, is thought to have posted messages urging violence against the event in the city of Garland, pre-empting the eventual attack.

The two armed men were shot dead by security after they opened fire outside the Muhammad Art Exhibit event, where participants were told to draw the Islamic prophet - considered blasphemy by his followers - for the chance of a $10,000 prize.

Hassan is believed to have posted a message on Twitter calling for the violence on April 23.

A twitter account believed to be his wrote: 'The brothers from the Charlie hebdo [sic] attack did their part. It's time for brothers in the #US to do their part.'

This was followed by a hyperlink to a news story describing the event, which took place at Garland's Curtis Culwell Center Sunday night.

The account which posted the message was named Mujahid Miski, believed to be Hassan's jihadi alias.
