At least two Turkish soldiers were injured in an attack in Turkey's southeastern Sirnak province on Tuesday, local security sources said.
According to the sources, members of Kurdistan Workers' Party (PKK) attacked a military base in Uludere district with long-barreled weapons.
The wounded were taken to the Sirnak military hospital.
Security forces have launched an operation in the area to nab the attackers.
Operations against the PKK -- listed as a terrorist group by Turkey, the EU and U.S. -- came after it renewed attacks on Turkish security forces following the July 20 Suruc bombing that killed dozens of people.
