At least 27 PKK terrorists have been killed, six others have been captured in nationwide anti-terror operations in the past week, Turkey's interior ministry said in a statement Monday.

According to the interior ministry, 10 PKK terrorists surrendered to security forces.

Police have also detained 285 people with suspected links to terrorist organizations.

Security forces confiscated an unmanned aerial vehicle (UAV), 16 weapons, 470 kilograms of explosive substance, nine hand grenades and ammunition, while nine hideouts used by the terrorists were destroyed.

Meanwhile, a statement by Hakkari Governor's Office released Monday said that four PKK terrorists have been killed in drone-supported airstrikes near Kırıkdağ region.

Founded in 1978, the PKK has waged a decades-long bloody campaign against Turkey.

The PKK, which is listed as a terrorist organization by Turkey, the U.S. and the EU, resumed its armed campaign in July 2015 after a brief reconciliation period.

Since that time, the PKK has been responsible for the deaths of some 1,200 security personnel and civilians, including women and children, while more than 4,000 security personnel and over 2,000 civilians have been injured.
