Police detain three with Semtex at Austrian border

Czech police said on Thursday they were holding three men who had attempted to smuggle 2.5 kg of the plastic explosive Semtex, a gun and other items into neighbouring Austria. Experts said the amount of Semtex - a powerful Czech-made explosive with a record of being used by terrorist groups - was enough to bring down an aircraft. A police spokeswoman said the group tried to cross the border in a car late on Wednesday evening. All were carrying Czech passports.
