ANKARA, Turkey -- Turkey's state-run television says a roadside bomb explosion has killed four policemen and two civilians, including a 2-year-old girl, in Turkey's southeast. Several other people were injured.

TRT television, citing local authorities, said the blast occurred in the town of Guroymak in Bitlis province as a police vehicle passed by. It says authorities have launched an operation to catch the culprits who are believed to be Kurdish rebels.

The rebels have lately intensified their attacks in a war for autonomy in the country's Kurdish-dominated southeast, killing dozens of members of the country's security force and at least 17 civilians since mid-July.

The conflict has killed tens of thousands of people since 1984.
