Baghdad, May 5 (IANS): The Islamic State (IS) militant group on Tuesday claimed responsibility for an attack on Sunday outside a US venue for conference on cartoons depicting Prophet Mohammed.
In a statement read on its al-Biyan radio station, the IS said that "two soldiers of the caliphate" opened fire at an exhibition where the conference was held in the city of Garland in Texas, Xinhua news agency reported.
"We tell America that what is coming is worse and more bitter, and that you will see from the soldiers of the IS what will aggravate you," said the statement.
The radio station is based in the IS-controlled city of Mosul in northern Iraq.
On Sunday evening, two men drove up to the Culwell Event Center in Garland, and opened fire when the "Draw Mohammad" contest and conference was coming to an end, wounding an unarmed security guard.
The two were shot dead by police.
The attack in Texas was the first inside the US to be claimed by the extremist group.
In January, a deadly attack killed 12 people at the Paris office of French satirical weekly Charlie Hebdo after it put an image of Prophet Muhammad on its cover.
Another deadly shooting occurred the following month at an event in Copenhagen featuring an artist who had caricatured the Prophet.
