Maoist cadres chanting "down with the puppet government" slogans today paralysed work in offices and clashed with ruling CPN-UML activists in several parts of Nepal as they intensified their anti-government agitation.

Curfew was clamped in the eastern Dhankuta district for an indefinite period after Maoist cadres clashed with activists of the ruling CPN-UML, police said, even as the security forces stood on high alert.

Shouting slogans of "down with puppet government," and "remove unconstitutional government", the Maoists demanded that President Ram Baran Yadav's "unconstitutional" move to reinstate Army chief Rukmangad Katawal be rectified.

Heavy security was in place throughout the capital but the protests here were peaceful.

In Kathmandu hundreds of Maoists carrying red flags picketed the District Administrative Office and prevented the government staff from entering the office.

Traffic was disrupted for hours in several places as the activists held demonstrations demanding restoration of "civilian supremacy".

In Nuwakot and Sunsari districts in central and southern Nepal, scores of Maoist cadres and policemen were injured as the agitating Maoist cadres clashed with the riot police.

All 75 districts of Nepal were affected due to the agitation and security has been tightened in government offices to prevent any untoward incidents.

Nepal is in the middle of a political turmoil since Prachanda resigned as Prime Minister in May following a confrontation with President Yadav over the sacking of the Army chief Rukmangad Katawal.

The Maoists have been blocking the Parliament since then demanding that the President rolls back his move of overturning a democratically elected government's decision.
