United States counterterrorism experts believe that terrorists with an “American face” will conduct any future attack, The Telegraph reported on Thursday.

Referring to reports of Westerners in terrorism training camps in Pakistan, the report quoted experts saying dozens of Westerners have undergone training, as terrorists try to recruit non-Middle Eastern Asians, particularly Caucasians, because they are less likely to attract the attention of security forces.

Al Qaeda’s recent decision to release videos in English and a similar change on extremist websites have also been cited of evidence of a new strategy to find foreign recruits, according to the report. Such concerns were sharpened last week after the arrest of three Germans over an alleged plot to destroy a club used by US servicemen. The Germans had allegedly been trained in camps in Waziristan.
