A landmine killed a Turkish officer on Friday near the southeastern Turkish borders with Iraq, said Turkish security sources. Turkish Ikhlas News Agency reported the governor office of Hakkari province as saying that the officer was killed after stepping on a landmine believed to be planted by members of the banned Kurdistan Workers Party.During the past few months, insurgents of the Kurdish party increased the ratio of attacks against Turkish army and strategic targets. The party began a military campaign against Turkey in 1984 in an attempt to establish an independent state in southeastern Turkey, which claimed the lives of more than 37,000 people.
