BERLIN, May 1 (UPI) -- More and more extremists from Germany are traveling to Pakistan and Afghanistan to plot terror attacks; a new video shows a German convert to Islam who calls on Islamists back home to follow his example.

The video that appeared Tuesday on a Turkish-language Web site threw German security experts into a frenzy: It showed a German Islamist from Neuenkirchen in the Saarland, whose "wanted" posters hang all over Afghanistan's capital, Kabul. German news magazine Focus identified him as Eric Breininger, a 20-year-old German who converted to Islam a few years ago. Together with his accomplice, identified by German news magazine Focus as Houssain al-Malla, Breininger is hiding somewhere in Afghanistan or Pakistan, experts say.

The video shows Breininger sporting a camouflage suit and a machine gun, according to the online version of German news magazine Der Spiegel. Breininger is lauding Cueneyt Ciftci, a 28-year-old Turkish national from Germany, who on March 3 drove a pickup truck full of explosives into a U.S. outpost in the province of Khost, killing two U.S. soldiers from the 82nd Airborne Division and two Afghan civilians.

The suicide bombing, Breininger said, was a "good deed" as it "sent to Hell" several nonbelievers. The man then continues to ask his "brothers in Germany" to follow his and Ciftci's example and join the Jihad in Afghanistan and Pakistan -- be it by traveling there, or by providing monetary or spiritual support.

German security experts have long feared Breininger and al-Malla are planning terror attacks like the one Ciftci carried out in March.
