Anger has erupted against the Turkish government after a deadly coal mine disaster in the western town of Soma.
People in Soma hurled abuse as they surrounded PM Recep Tayyip Erdogan's car during his visit to the scene of the tragedy, and protesters clashed with police in Istanbul and Ankara.
An explosion on Tuesday caused the pit to collapse, killing at least 274.
The latest rise in the death toll means it is the worst such incident in the country's history.
Rescuers are still hunting desperately for scores of miners who are missing but feared dead.
Nearly 450 workers have been rescued, according to the mine operator. However, no survivors have been found in the last few hours and more than 100 are still unaccounted for.
Eighty of those rescued had been treated for injuries, none of which were described as serious.
