Voters in Central African Republic are returning to the polls to cast ballots in a historic presidential runoff vote.

The long awaited election is being held after more than two years of sectarian fighting between Muslim and Christian communities left thousands dead and nearly 1 million people displaced.

Armed U.N. peacekeepers stood guard as voters lined up to vote Sunday in the Fatima neighborhood of the capital. Some people were angered because their names were not on the list at their voting center, while others did not have the necessary photo identification.

Authorities said they were working on a solution to the problem as many of the voters said their IDS were lost as homes were burned to the ground during the conflict.
