A Pakistani intelligence official says eight Germans and two British brothers are behind a recent terror plot against European cities.
The official, who spoke on the condition of anonymity, said one of the Britons died in a recent CIA missile strike. Pakistan intelligence authorities are tracking the remaining suspects.
Investigators believe the suspects are involved in planning a terror plot to wage Mumbai-style shooting sprees in Britain, France, and Germany.
"They have been making calls to Germany and London," the official said. "They have been talking about and looking for facilitators and logistics they need there to carry out terror strikes."

European and U.S. officials said the plot was still in its early stages and not considered a serious threat. Still, extra precaution was taken, with officials temporarily evacuating the Eiffel Tower, Tuesday, and increasing security around Buckingham Palace, Trafalgar Square, and Big Ben.
Meanwhile, an employee at Pakistan's state-run Islamic advisory board has been detained for allegedly assisting the failed Times Square car bomber, Faisal Shahzad.
The suspect accompanied Shahzad to northwest Pakistan to meet militant leaders, according to a Pakistani intelligence officer.
