Security sources in Turkey say four civilians have been killed in a blast by a landmine planted by suspected Kurdish rebels in the southeastern part of the country.
Turkey's semi-official Anatolia news agency reported Sunday that the explosion took place after some members of the Kurdistan Workers' Party, or PKK, set fire to an oil well in Batman province.
Clashes between Turkish forces and Kurds have increased since the PKK called off a yearlong cease-fire in June. The group cited repeated Turkish military attacks for ending the truce.
The PKK has been fighting for Kurdish autonomy in southeastern Turkey for more than 25 years.
Turkey, the United States and the European Union classify the PKK as a terrorist group.
