Members of the Human Rights and Peace Society Nepal staged a demonstration outside the UN House in Pulchowk of Kathmandu on Tuesday demanding that the United Nations take effective steps against Myanmar’s military junta government’s use of excessive force on pro-democracy protesters.

Myanmar has been in turmoil since the army ousted an elected government led by Nobel laureate Aung San Suu Kyi, detaining her and reimposing military rule after a decade of tentative steps towards democracy.

At least 521 civilians have been killed in two months of protests against the Feb. 1 coup, 141 of them on Saturday, the bloodiest day of the unrest, according to the Assistance Association for Political Prisoners (AAPP).

A civil disobedience campaign of strikes has paralysed parts of the economy and protesters stepped it up by asking residents on Tuesday to leave rubbish at city intersections.

Western countries have condemned the coup and the violence and called for Suu Kyi’s release, and some have imposed limited sanctions.
