The Nepali Congress-aligned Nepal Students Union (NSU) enforced hour-long 'chakkajam' (traffic blockage) in front of government colleges in the capital and elsewhere Tuesday morning to protest the police action during Monday's NSU demonstration against Prime Minister Baburam Bhattarai at the airport when he arrived there from Brazil.

The NSU cadres also staged demonstration as they blocked the traffic. There was traffic snarl for some time on the roads in the central Kathmandu because of the protest.

Nearly four dozen NSU cadres were briefly taken into custody -- with few others injured in the baton-charging --when they were chanting slogans and waving black flags near the entrance of the international airport when the PM's convoy arrived there.

The NSU cadres had also waved black flags at the PM at the airport gate last week to protest PM's visit to Brazil. They had smashed the windows of the car carrying German ambassador who was at the airport to see the PM off. nepalnews.com
