Vote counting was underway in some polling stations in Guinea Sunday evening in the referendum on a draft constitution that could allow the leader of the country’s junta to run for the presidency.

The referendum, which is a key step in the country’s transition from military to civilian rule, is being closely monitored in the coup-battered region, with critics calling it a power grab.

Some say it is a way for General Mamadi Doumbouya, who took power by force four years ago, to seek the presidency and legitimize his military rule.

Lawyer Mamadou Diouhe Diallo said he didn't register to vote, because the constitution would allow Doumbouya to remain in power, despite his promises that he would not do so.

Meanwhile, baker Mabinty Kalabane said she is "confident" in the referendum after reading many articles.

Guinea is one of a growing number of West African countries, including Mali, Niger and Burkina Faso, where the military has taken over.

There are 6.7 million eligible voters and the referendum needs a turnout of at least 50% to pass. Polls opened at 7 a.m. local time and were expected to close at 6 p.m. Some stations extended voting time.

The referendum has been organized by the Directorate General of Elections, a new body that will oversee the vote count and whose two heads were elected by Doumbouya.

Elections are expected to follow in December.
