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.

It's unclear exactly what a "temporary security zone" is, but it is very likely these are areas where the Turkish military will try to restrict any kind of movement in or out.

June 3, 3007: Turkish artillery shelled the Hakurk area (east of the Iraqi border town of Zakho). Turkey believes the area is used as an infiltration route for PKK guerrillas moving from bases in Iraq into Turkey.

May 28, 2007: Turkey believes some 3,800 PKK rebels are currently based in Iraq, and about 2,300 are operating inside Turkey.

May 25, 2007: The Turkish government complained that it is not receiving the support it expected from the US in its fight against the PKK, and that the US diplomatic effort "is not at the desired level…"
