AFPVilnius (AFP) - Lithuania said Monday it plans to use EU funds to build a fence on the border with Russia's highly militarised Kaliningrad exclave to boost security and prevent smuggling. Baltic states have repeatedly voiced their concern at the Russian military build-up in the exclave sandwiched between Poland and Lithuania, both EU and NATO members. Construction of the 130-kilometre (80-mile) fence will start this spring and will be finished by the end of the year, Interior Minister Eimutis Misiunas told AFP. "The reasons are both economic to prevent smuggling and geopolitical to strengthen the EU's external border," he said.
