Gunfire, a grenade explosion and threats of violence in Central African Republic on Sunday prevented many from voting in a constitutional referendum seen as a test of whether national elections can take place later this month.
An attack on a voting station in the PK5 neighborhood by gunmen killed at least one person and injured six others, said a Muslim community leader Ousmane Abakar .
A grenade exploded near a voting center in the northern Gobongo neighborhood of Bangui, injuring three people, residents said.
The referendum for which 2 million people were registered to vote at more than 5,500 stations continued elsewhere, though there were reports of missing voter cards.
The U.N. mission in Central African Republic currently has more than 11,000 troops and police are trying to calm the deadly violence.
