The arrests were made by the local gendarmerie and members of the country's intelligence service in Mardin province.
Turkish gendarmerie and intelligence forces arrested a YPG/PKK terrorist in southeastern Turkey during a joint anti-terror operation on Monday.
According to security sources, local gendarmerie and members of the country's intelligence service arrested a member of the YPG/PKK terrorist group and another suspect in Mardin province.
Operations are ongoing to capture the owner of the house, sources said.
Another YPG/PKK member on the run from the group surrendered to Turkish security forces in Sirnak province on Monday evening.
According to security sources, the man ran away from a YPG/PKK training camp in northern Iraq.
YPG/PKK often use northern Iraq to plan cross-border terrorist attacks in Turkey.
The YPG is the Syrian offshoot of the PKK terrorist organisation. In its 30-year terror campaign against the Turkish state, more than 40,000 people, including women and children, have been killed.
Turkey, the US and the EU recognise the PKK as a terrorist organisation.
