Vote counting is underway in Ethiopia after millions of citizens cast ballots in a parliamentary election widely expected to hand Prime Minister Abiy Ahmed and his ruling Prosperity Party another five-year term, despite security incidents, opposition concerns and ongoing conflicts.

Polling stations closed late Monday night across Ethiopia, with vote counting beginning early Tuesday after millions of citizens took part in legislative elections.

Authorities extended voting by six hours, keeping polling stations open until midnight to accommodate high turnout in several areas.

More than 50 million people were registered to vote in the election, which will determine the composition of the House of Representatives and ultimately the country's next prime minister.

Results are expected within days, with the National Electoral Board indicating a final announcement could come by June 11.
