Excerpt:
Arid Uka was a typical product of Frankfurt, a city where a third of the population is not originally from Germany. An ethnic Albanian born in Kosovo and raised Muslim, he grew up in a middle-class family in Germany and lived with his parents and siblings. It was only recently that he turned to radical Islam, apparently connecting with extremists on Facebook and online jihadi forums.
On Wednesday, Mr. Uka became the first person to successfully carry out a terrorist attack in Germany since 9/11. He has been charged with killing two US airmen and wounding two others at the Frankfurt airport in an act that German prosecutors say Uka carried out on his own. In court Thursday, he confessed to the killings and said he shot the four men because he felt America was at war with Islam.
"We have a new ... perpetrator of terrorism, the lone wolf," says Bernd Georg Thamm, a security expert based in Berlin. "Terrorism experts have dreaded this for a while, and now it's happened. And it won't be the last case."
