REPUBLIKA.CO.ID, KATHMANDU -- An Indian national was killed Monday when Nepal police fired into a crowd of protesters who were trying to block a border checkpoint, a spokesman said.

"Police warned the protesters to disperse but they did not listen, compelling security forces to open fire," said Nepal police spokesman Kamal Singh Bam.

"An Indian national was wounded and died after being taken to hospital."

Four police suffered injuries in clashes with demonstrators at the checkpoint in the southern town of Birgunj, around 90 kilometres (55 miles) south of Kathmandu, Bam told AFP.
