A spokesman for Aung San Suu Kyi's opposition National League for Democracy says 13 party members were arrested in Burma just days before the country's military government released some 5,000 prisoners.
Party spokesman U Lwin says the 13 were detained December sixth in Bogalay Township, southwest of Rangoon. He said they were accused of trying to incite unrest.
Burma state media said Monday that some 5,000 prisoners had been released during the past few days. The military government says many were illegally jailed by the now-defunct National Intelligence Bureau.
Opposition members say only 11 political prisoners were among those released.
