Turkish troops killed four Kurdish guerrillas in a southeastern province on Wednesday, a day after police defused a bomb in the capital that authorities believe may have been planted by Kurdish rebels.
The clash erupted in the southeastern province of Siirt, the local governor's office said, and was the latest bout of fighting this year between soldiers and the separatist rebels, who have bases in neighboring Iraq and have been battling the Turkish state since 1984.
On the sixth anniversary of the Sept. 11 attacks in the United States, authorities discovered more than 600 kilograms, or 1,320 pounds, of explosives packed into a minibus parked near a marketplace in Ankara, preventing a possible bomb attack.
Police were looking for the driver of the minibus, reported the state-run news agency, Anatolia. A witness said an unidentified man parked the minibus at a multilevel parking lot near a market place around 4 pm Monday, saying he was bringing goods to sell at the food market, the agency said.
