A US citizen has carried out a suicide bombing in Syria, making him the first American to be involved in such an attack, reports said.
The American worked with al Nursa Front, a group linked to al Qaeda, CBS news said.
In a series of tweets, the group identified him as Abu Hurayra al-Amriki, or Abu Hurayra the American, according to NBC.
The man, whose real name has not been released, is believed to have carried out an attack in northern Syria on Sunday.
The area has seen increased fighting in recent weeks.
Photos circulated on extremist Islamist sites showed a bearded man, a cat in his arms, who was said to be the bomber, the New York Times said.
Western officials have expressed worry that citizens travelling to Syria from countries such as the US or Britain get radicalised and train as terrorists.
Some officials have said those citizens may pose a threat once they return to their home nations.
Around 400 Britons are believed to have gone to Syria over the last two years to train in camps or take part in the fighting, with an estimated 20 having died.
Officials in the UK have advised those who want to support humanitarian efforts in Syria to donate to charities instead of going there.
