A car bomb has struck a police vehicle in the southeastern Turkish city of Diyarbakir, killing three people.
The governor's office said 45 people, including 12 police officers, were also wounded in the May 10 blast.
There was no immediate claim of responsibility for the attack, which took place in the center of the largely Kurdish city.
Earlier on May 10, two police officers were killed while attempting to defuse a roadside bomb in the eastern province of Van, the state-run Anatolia news agency reported.
Violence in southeastern Turkey has surged since a fragile peace process between the state and the rebels of the outlawed Kurdistan Workers' Party (PKK) collapsed in July 2015.
Hundreds of people, including many security force members, have died in the renewed conflict.
