Voters in the Democratic Republic of Congo are voting on a new constitution that aims to bring stability to the war-torn nation.
Sunday's referendum is the first free, democratic poll the DRC has held in some 40 years.
Election authorities report substantial voter turnout in most of DRC's 11 provinces. But they say voter participation in the capital, Kinshasa, was low during the morning, perhaps because of church attendance. Some opposition parties had called for a boycott of the election.
Some polling places opened late. Authorities said polling places with long lines at closing time Sunday will open again Monday to allow everyone a chance to vote.
