Kurdish rebels launched a suicide attack Sunday at a military police post in eastern Turkey, killing two soldiers and wounding 24 others.
The local governor's office said the attack in Agri province, near the Iranian border, involved an agricultural vehicle packed with two tons of explosives.
In a separate attack, one Turkish soldier was killed and four others wounded in the southeastern Mardin province when their military vehicle struck a land mine believed to have been laid by the rebels
The casualties were the latest in an increased spate of violence between the Kurdistan Workers Party (PKK) and Turkey, which began a series of airstrikes just over a week ago targeting the Kurdish rebels inside Turkey and in northern Iraq.
Official Turkish media says government forces have killed 260 Kurdish militants in the offensive and injured another 400.
The president of Iraq's Kurdistan region issued a statement Saturday urging the two sides to resume a peace process.
Massud Barzani said the PKK should withdraw from Iraq's Kurdish territory in order to prevent civilian casualties from the airstrikes, while also criticizing Turkey's aerial campaign.
"We condemn the bombing, which led to the martyrdom of citizens of the Kurdish region, and we call on Turkey not to repeat the bombing of civilians," Barzani's office said.
Barzani's Kurdistan Democratic Party has often had disputes with the PKK, but has allowed its fighters to take shelter in remote mountain regions on the Iraqi side of the border.
