Central African Republic (CAR) will delay elections, which were set to take place on Sunday, until December 30, Prime Minister Mahamat Kamoun said on Thursday.
Kamoun said that they had to suspend the elections because ballots did not arrive on time and poll workers need to be trained.
"We need to do this with proper material in order to avoid fraud. The delay is necessary if we want to have good results," Kamoun said.
In the former French colony, elections have been delayed many times. CAR has been governed by an interim government, which is the second one since PM Francois Bozize was overthrown in March 2013.
Nearly one in five Central Africans have left the country, which is rich in uranium, gold and diamonds. The clashes between Christian militants, who are aiming to eliminate Muslim residents from the Central African Republic, and Muslims have intensified.
According to Amnesty International report on August, more than 30,000 Muslims moved to seven enclaves across the country guarded by UN troops, but for those who have not sought refuge in one, are living under constant fear of being targeted for their religious beliefs.
More than 6,000 people have been killed and more than one million people displaced since Muslim-led Seleka rebels took control of the capital in March 2013.
