ANKARA, Sept. 9 (Xinhuanet) -- Four members of the outlawed Kurdish Workers' Party (PKK) were killed in eastern Turkey, an official statement said on Friday.

    The statement issued by Tunceli Governor's Office said Turkish security forces killed the four PKK members including one woman in a clash in rural areas of Cicekli village in Tunceli province.

    The statement added that an operation is underway in the region. 

    Meanwhile, Turkish security forces killed a terrorist in Yaylakonak village of Hinis township in Erzurum province.

    The PKK has launched a series of landmine and remote-controlled bomb attacks in Turkey over the past few months.

    The group took up arms for Kurdish independence in southeastern Turkey in 1984 and its conflicts with government forces have claimed some 37,000 lives since then.

    Last month, Turkish Prime Minister Recep Tayyip Erdogan made a speech in Diyarbakir in southeastern Turkey. In response to his call for laying down arms, the PKK announced a one-month ceasefire from Aug. 20 to Sept. 20.  Enditem
