[JURIST] Myanmar's military government has arrested more than 20 peaceful demonstrators protesting the scheduled May 10 national constitutional referendum [JURIST report], the opposition National League for Democracy (NLD) said Tuesday. The NLD also said that government security forces have detained a close aide of pro-democracy leader Aung San Suu Kyi [BBC profile; JURIST news archive].

The military junta has also rejected calls for international observers. Earlier this week, UN Special Rapporteur on Myanmar Paulo Sergio Pinheiro criticized the timing of the referendum, saying it was "surreal" to hold a referendum while the military government continues to persecute critics of the proposed charter.
