In Sirnak province's Cizre district, security forces spotted seven Kurdistan Workers Party (PKK) fighters entering Turkey from Syria on Tuesday evening and as they clashed one soldier was killed and one wounded, the Turkish armed forces said.
Another Turkish soldier was shot dead on Tuesday by PKK militants in the Sur district, under curfew since early December, of mainly Kurdish southeast Turkey's largest city Diyarbakir, the armed forces added in a statement, Reuters reported.
Turkish security forces have been trying to clear southeastern towns and cities of PKK militants since last July, when a two-year ceasefire collapsed, shattering a peace process and triggering the worst violence in two decades.
Separately, one police officer was killed and one wounded when PKK rebels launched a rocket attack on an armoured vehicle in the town of Sirnak, state-run Anadolu Agency reported on Wednesday. It was not clear when the attack occurred.
The PKK, which says it is fighting for autonomy for Turkey's large ethnic Kurdish minority, is considered a terrorist group by Turkey, the United States and the European Union. The 31-year-old conflict has cost more than 40,000 lives.
