At least 27 people have been confirmed to have died after a ferry capsized off the coast of Guyana over the weekend, the country's Prime Minister Mark Phillips said Monday.

Another 83 others are still missing as a search and rescue operation continued.

Phillips said that 69 people had been rescued from the vessel that had been transporting around 180 people when it overturned.

"Our focus again is on finding people," Phillips said, after raising the death toll from a previous 10. "We still have hope."
