Twelve Turkish soldiers were injured Wednesday in southeast Turkey when their bus hit a landmine. The Anatolia News Agency said five of those injured are in very critical condition, adding that the blast took place when the soldiers were carrying out a routine combing campaign at the Hakari neighborhood close to the Turkey-Iraq-Iran border triangle.This blast coincides with the massing of more Turkish troops at the mostly resided Kurdish south eastern areas in preparation for launching a wide scale offensive against the separatist Kurdish Labor Party members. Earlier, Turkey announced that 3,500 Kurdish separatists are taking positions in north Iraqi mountainous areas and setting the stage for launching terrorist attacks inside Turkey.
