LONDON (AFP) - Five illegal immigrants were caught at a British military base after stowing away in a convoy of army vehicles returning from Kosovo, police said Thursday. Two Indians, aged 24 and 26, two Afghans aged 16 and 18, and a 15-year-old Iranian were discovered Tuesday by soldiers at the Duke of Gloucester Barracks, in South Cerney, in western England. Gloucestershire Police said they are believed to have climbed on board the convoy returning from Kosovo at the French port of Calais. The Sun tabloid said in its edition Thursday that the lorries were driven by civilian contractors being supervised by soldiers. The immigrants were found after protective canopies on the trucks were removed. The five were given food and water before being arrested and handed over to the immigration authorities. Senior army officials have ordered a review of security arrangements at the base.
