More than 5,000 CNRP supporters marched through Phnom Penh on Sunday after opposition party leaders Sam Rainsy and Kem Sokha announced the beginning of what they said would be a non-stop mass demonstration until the CPP government of Prime Minister Hun Sen calls a new election. A small squadron of traffic police walked about 100 meters in front of the protesters throughout the hour-long march, which studiously avoided major government buildings as it snaked along Monivong, Kampuchea Krom, Jawaharlal Nehru and Charles de Gaulle boulevards before returning to Freedom Park.
