DIYARBAKIR, Turkey (Reuters) - A car bomb killed three people and wounded 45 when it struck a police vehicle on Tuesday in Diyarbakir, the main city in southeastern Turkey where security forces are trying to crush a Kurdish militant insurgency, the governor's office said.
Explosives in the vehicle were detonated from a distance as an armoured police van passed, wounding 12 police officers, the governor's office said. A Reuters witness heard a big explosion in the city centre, followed by ambulance sirens. Black smoke rose over the site and debris was scattered along a wide avenue.
Five of the wounded were inmates being moved while under police custody, a security source said. A senior official said some of them were members of the outlawed Kurdistan Workers Party (PKK) militant group being taken to hospital and that they may have been targeted for being suspected informants.
The PKK has waged a three-decade insurgency against the Turkish state to push for Kurdish autonomy in the southeast. It is considered a terrorist organisation by Ankara, the European Union and the United States.
Parts of Diyarbakir and other towns in the region bordering Syria, Iraq and Iran have seen intense security operations since conflict between the state and PKK re-ignited in July 2015.
Hundreds of police and soldiers and thousands of PKK fighters have since been killed, according to official figures. Opposition parties say more than 500 civilians have also been killed.
