According to NTV television, an improvised bomb placed in a sewer exploded on a street of the Silopi township as a police car was passing by. There are five policemen among the wounded.
Authorities suspect Kurdistan Workers' Party (PKK) involvement in the attack, NTV said.
Ankara has imposed several round-the-clock curfews in Kurdish-populated towns, preventing civilians from fleeing the regions where the military operations are taking place.
In April, a member of the Turkish parliament from the Kurdish People's Democratic Party told Sputnik that the town of Silopi was under a blockade with a curfew in place, while the authorities were trying to drive the Kurds from the town of Cizre.
