"Turks Raid, Not Invade, Iraq
June 8, 2007: Turkish special forces troops, in helicopters, landed inside Iraq, attacked a PKK target, then left. Turkish special ops units frequently pursue PKK rebels across the border ('hot pursuit'). They also cross the border on recon missions and meet with Iraqis (unofficial meetings to discuss subjects like preventing attacks, etc). Elsewhere, a bomb attack killed three Turkish soldiers and wounded six in one of the Turkish military's new 'temporary security zones' south of the Turkish city of Siir, near the Iraqi border."
