Singapore: Iranian students in green facemasks have gathered in Singapore to condemn what they called a fraudulent presidential election last week and subsequent government crackdown on demonstrations in their homeland.

About 70 graduate students from the Nanyang Technical University and National University of Singapore held signs on Friday alleging human rights abuses by the government at a park in downtown Singapore.

The protesters call on Iran's government to hold another vote and stop violence against demonstrators.

The protest lasted about 30 minutes at "Speaker's Corner," where the government allows some public demonstrations which are banned elsewhere on the island city-state.
