Ahmad Feras Diri, a dual citizen of the UK and Syria, was extradited to the US on 12 November 2015. Diri has been charged with conspiring with his brother and others to evade US export laws and illegally send chemical laboratory equipment to Syria. He had been arrested in London in March 2013 in connection with the pending charges. The equipment allegedly exported includes portable gas scanners to detect chemical warfare agents, handheld field instruments to detect and classify toxic chemicals, gas masks, industrial engines for use in oil and gas field operations, and a device to locate buried pipelines.
