The United Nations has welcomed the participation of the opposition parties of Bangladesh in the just-held elections for the first time in 10 years.

"We call on all sides to exercise restraint and ensure a peaceful post-electoral environment, where people can maintain their right to assembly and expression," said the UN spokesman on Monday.

 Awami League has won the election with absolute majority.

In a note on the polls, the spokesman said the United Nations is aware of violent incidents and reports of irregularities in the general election.

"We regret the loss of lives and injuries sustained by candidates and voters during the electoral campaign and on the election-day," the note reads.

The UN encouraged the parties to address electoral complaints in a peaceful manner and through legal means.

"Violence and attacks on people and property are not acceptable," said the UN spokesman.
