LONDON, Sept. 30 (UPI) -- There may be as many as 20 British Muslims training for strikes against possible targets in Europe, including the United Kingdom, intelligence sources said.
Europe is on high-alert following allegations that terrorists in Pakistan were plotting commando-style raids on targets in Western Europe.
Intelligence sources told British newspaper The Daily Telegraph that "there are 15 to 20 Britons" training for attacks at camps in Pakistan.
Intelligence officers who spoke to the newspaper on condition of anonymity said the Britons were trained in the use of firearms and explosives.
The British intelligence service MI5 said the European attacks were traced from Pakistan to Britain. Authorities said some of the information on the European plot was linked to Ahmed Sidiqi, a German national arrested in July who revealed details of the attacks to interrogators in Afghanistan.
MI5, the Telegraph adds, is upset that information about the plot was revealed while intelligence officials were still connecting the dots.
"This is an ongoing operation with a constantly changing dynamic," a security source said. "There are local, national and international links, including Pakistan."
