Mark Oberholtzer isn't an Islamic fighter in Syria. He's never been to Syria. And the plumber from Texas City, Texas, says he certainly would never willingly aid fundamentalist rebels.
So it's hard for him to understand how his Ford F-250 pickup truck - including his logo for Mark-1 Plumbing and his phone number - wound up in a propaganda picture sent out by the extremist Ansar al-Deen Front from the front lines of the war in Syria.
Mr Oberholtzer says he's been getting hundreds of phone calls and faxes since the Ansar al-Deen Front tweeted a picture of his old truck with an anti-aircraft gun in the back, according to the Galveston County Daily News.
