Twelve people fave been found dead after a Turkish police helicopter crashed in the eastern province of Tunceli on Tuesday, the local governor's office said, blaming the crash on poor weather conditions.

The helicopter was carrying a judge, seven police officers, one sergeant and three crew members, the Tunceli governor's office said in a statement.
Heavy fog in the region made the rescue operation for the Sikorsky S-70 Black Hawk helicopter difficult, reporters said.
