The European Union has deployed more than 100 observers in polling stations throughout much of the country.
In Kidal, three people were injured when supporters of the Tuareg National Movement for the Liberation of the Azawad threw stones at voters waiting in line outside a polling station, prompting U.N. peacekeepers to intervene, said Kidal resident Mohamed Ag Mossa.
There were also scattered reports of registration problems early on Sunday.
“I didn't see my photo or my name on the list,” said Bintou Maiga, who was turned away from her assigned polling station in Gao. “I'm disappointed now because I wasn't able to vote.”
A runoff vote, if necessary, will be held on Dec. 15.
