Tension broke out in Butwal on Thursday after the demonstrators hit the streets to protest against the constitution amendment bill that proposes to separate Tarai and hill districts in province number 5. The demonstrators and security personnel hurled stones at each other turning the area into a virtual battleground. Tension escalated after youths carrying national flags started vandalising Maoist's Sahid Smarak and statue along the hospital line today to protest the amendment bill. The irate youths broke a wall defying the police security. They also pelted stones on security personnel that triggered police to resort to using force. Hundreds of demonstrators were seen on the streets. The situation has not calmed down yet. However, no group or organisation that spearheaded the protest was seen during the protest. The All Nepal National Free Student Union (ANNFSU), student wing of the main opposition CPN-UML, among other student unions have called for a an indefinite Rupandehi banda. ANNFSU Rupandehi district Chair Balkrishna Pandey said they were conducting a peaceful protest and were not involved in vandalism. He said action should be taken against the guilty. "Our province is being divided and we are protesting with a heavy heart. If any activities or arsons are reported that must be due to infiltration of other groups," said Chairman Pandey.
