ISLAMABAD — Dozens of Muslim militants with European citizenship are believed to be hiding out in the lawless tribal area of northwestern Pakistan, Pakistani and Western intelligence officials said Sunday, training for missions that could include terror attacks in European capitals.
Officials have used phone intercepts and voice tracking software to track militants with ties to Britain and other European countries to areas along the Afghan border. Al-Qaida would likely turn to such extremists for a European plot because they can move freely in and out of Western cities.
Fear that such an attack is in the planning stage has prompted the US State Department to advise Americans traveling in Europe to be vigilant. American and European security experts have been concerned that terrorists based in Pakistan may be plotting attacks in Europe with assault weapons, similar to the deadly 2008 shooting spree in Mumbai, India. US intelligence officials believe Osama bin Laden is behind the plots.
