CBS, AP and others say that Turkish troops have crossed the international border between Turkey and (technically), Iraq, to enter Kurdish territory, allegedly in "hot pursuit" of terrorists or guerrillas, (depending on taste). "Several thousand" troops are involved, say "Turkish security officials" talking to AP.
Meanwhile the Turkish Foreign Ministry denies any such thing has happened -- no Turkish troops were ever there. If they, hypothetically, might be there, it's evidently a "hot pursuit" and not an "incursion." No doubt that's a significant difference to somebody.
Back on 25 May, the Turkish Foreign Minister said Turkey had no immediate plans to send troops to Iraq. If the Turks were not and are not -- planning or doing anything, they are sure talking a lot about Kurdistan.
The Kurds have been a problem for the Turks for quite a while. What has changed ? Are the Turks positioning themselves to take care of quasi-independent Kurdistan once the Americans leave ?
