A Turkish soldier was killed and three others wounded in the southeast of the country on Wednesday after two mines were detonated by suspected Kurdish guerrillas, officials said. The soldier was killed in Sirnak province, a remote area bordering Iraq. Separately, three members of the Turkish security forces were wounded when another remote-controlled mine exploded in Siirt province, local governor offices said. Tensions have risen in the mainly Kurdish southeast amid an upsurge in violence between Kurdistan Workers Party (PKK) fighters and the Turkish military after the PKK called off its unilateral ceasefire last year, Reuters reported.
