SARAJEVO, Dec 29 (Reuters) - Serbian police have arrested an Afghan army general and a sniper wanted by France on terrorism charges during a raid on an migrant camp in the north of the Balkan country, Tanjug news agency reported on Thursday.France had issued an international warrant for the two men, police told Tanjug.In a statement, police said the arrests were made at the makeshift camp near the northern town of Subotica, where 109 illegal migrants were found, 29 of whom were "interesting security-wise".Last month, Serbian police uncovered 600 illegal migrants near its northern border with Hungary following a shootout in a town in which one person was wounded.The Western Balkans route via Turkey, Bulgaria, North Macedonia and Serbia is the main path for migrants into the European Union, with many using elaborate networks of smugglers who are sometimes armed."
