Operation Steel (Turkish: Çelik Harekâtı) was a cross-border operation by the Turkish Armed Forces into northern Iraq between 20 March and 4 May 1995 against the Kurdistan Workers' Party (PKK). The purpose of offensive was to put a stop to the PKK cross-border raids and to crush the insurgency. Operation didn't put an end to the PKK.
On March 20, 1995, some 35,000 Turkish troops launched an invasion into Northern Iraq. The effect of the attack was however relatively limited, despite high PKK casualties, as the majority of the PKK forces left the region before the offensive begun as they had noticed the military buildup on the border and were anticipating the offensive. By April 25, Turkey pulled out 20,000 of its 35,000 troops. After on May 3, the Kurdistan Democratic Party delegation to Turkey said they would stop PKK activities in Iraqi Kurdistan, Turkey withdrew its remaining forces on May 4. The military operation strained relations between Turkey and the United States and Europe as over 15,000 Iraqi Kurdish civilians were displaced by Turkish forces.
More than 35,000 troops took part in the operation. Turkey announced fatalities at a total of 64 personnel made out of 4 commissioned officers, 5 noncommissioned officers and 55 soldiers. Turkey announced the injured at a total of 185 personnel made out of 13 commissioned officers 8 noncommissioned officers and 164 soldiers. Turkey announced the total number of militants neutralized at a total of 568 with 555 being killed and 13 being captured live or injured. The PKK claimed they killed 261 soldiers and only 18 of their fighters were killed during the operation.
