Flow of Western terrorist recruits increasing

U.S. and European counterterrorism officials say a rising number of Western recruits -- including Americans -- are traveling to Afghanistan and Pakistan to attend paramilitary training camps. The flow of recruits has continued unabated, officials said, in spite of an intensified campaign over the past year by the CIA to eliminate al-Qaeda and Taliban commanders in drone missile attacks.

Since January, at least 30 recruits from Germany have traveled to Pakistan for training, according to German security sources. About 10 people -- not necessarily the same individuals -- have returned to Germany this year, fueling concerns that fresh plots are in the works against European targets. "We think this is sufficient to show how serious the threat is," said a senior German counterterrorism official who spoke on the condition of anonymity.

German security services have been on high alert since last month, when groups affiliated with the Taliban and al-Qaeda issued several videos warning that an attack on German targets was imminent if the government did not bring home its forces from Afghanistan
