Ten Turkish soldiers were killed Monday in the country's restive south-east in two separate incidents being blamed on the Kurdistan Workers' Party (PKK), the Dogan news agency reported.
Four soldiers were killed and six members of the security forces injured in a roadside bombing in Mardin province.
Later, six soldiers were killed and one injured in clashes in Sirnak province, about 150 kilometres to the east. The attackers used rockets and assault rifles, the report said.
The mayor of Idil, a district in Sirnak from a pro-Kurdish party, was recently arrested, following the removal of more than 24 mayors in the mostly-Kurdish south-east who were replaced by trustees appointed by the government in Ankara.
The ceasefire and peace talks between the PKK and the government collapsed last year. Since then, more than 2,000 people - including civilians, members of the security forces and militants - have been confirmed dead in renewed violence.
More than 40,000 people have died in the 30-year war between the sides, with the PKK, which Ankara deems a terrorist group, demanding greater autonomy and rights for the Kurdish minority in Turkey, which often complains of systemic discrimination.
