ANKARA, April 18 (Xinhua) -- A Turkish police helicopter carrying 12 people disappeared from radar and crashed in the eastern province of Tunceli on Tuesday, the local governor's office said.

The helicopter was carrying one judge, seven police officers, one sergeant and three crew members, the Tunceli governor's office said in a statement.

The weather condition is poor, and heavy fog in the region made the rescue operation difficult, Turkish media reports said.

The contact with helicopter was lost at 11:50 a.m., according to the officials.

Teams of the Turkish Disaster and Emergency Management Authority (AFAD) were dispatched to the area between Ovacik and Pulumur of Tunceli for searching efforts.
