Turkish troops killed two separatist Kurdish rebels in fighting near Turkey's border with Iraq, the military said Sunday. The two were killed Saturday in rugged terrain in Sirnak province, when troops opened fire on a group of rebels who ignored calls to surrender and fired on soldiers, the military said in a statement posted on its official Web site. A day earlier, the military said it had fired on a group of about 50 to 60 guerrillas of the Kurdistan Workers' Party, or PKK, inside Iraqi territory, inflicting "significant losses." The attack occurred "inside Iraqi borders," southeast of Cukurca, a Turkish border town in Hakkari province, the military said. Hakkari, where rebels are active, is in the southeast corner of Turkey and shares a border with Iran as well as Iraq.
