Hakkari Governor Muammer Turker said that three soldiers of Turkish security forces were injured in Tuesday's attack staged by members of the outlawed Kurdish Workers' Party (PKK) in Hakkari province of southeastern Turkey, the semi-official Anatolia news agency reported. The PKK rebels opened fire on a military unit in mountainous Uzundere region of Cukurca town in Hakkari near the Iraqi border in evening hours on Tuesday. Turker said the injured soldiers had been sent to Hakkari Military Hospital and a wide-scale air-backed operation had been launched in the region to capture the PKK members that staged the attack. Anatolia early reported that two soldiers were wounded in the armed attack. Later Sunday night, PKK members attacked on a military vehicle carrying troops to their sentry posts in the naval logistics base with RPG-7 rocket launchers and long-range weapons in Iskenderun town of Hatay province in southern Turkey, killing six Turkish soldiers and wounding seven others. The past weeks have seen more clashes between the PKK and the military in southeastern Turkey as the weather warmed up. On May 20, Turkish armed forces killed 19 PKK members including some camp leaders in an air strike against some 50 PKK targets in north Iraq's Hakurk, Zap and Qandil regions, where a large number of PKK militants hide out in the mountains, according to Anatolia. The PKK took up arms in 1984 to create an ethnic homeland in southeastern Turkey and is listed as a terrorist organization by the Turkish government, the United States and the European Union. Some 40,000 people have been killed in conflicts fuelled by the PKK's separatist campaign in Turkey.
