As if things weren't complicated enough

As if things weren't complicated enough:

Turkey and Iran have dispatched tanks, artillery and thousands of troops to their frontiers with Iraq during the past few weeks in what appears to be a coordinated effort to disrupt the activities of Kurdish rebel bases.

Scores of Kurds have fled their homes in the northern frontier region after four days of shelling by the Iranian army. Local officials said Turkey had also fired a number of shells into Iraqi territory.

Some displaced families have pitched tents in the valleys behind Qandil Mountain, which straddles Iraq's rugged borders with Turkey and Iran. They told the Guardian yesterday that at least six villages had been abandoned and one person had died following a sustained artillery barrage by Iranian forces that appeared designed to flush out guerrillas linked to the Kurdistan Workers Party (PKK), who have hideouts in Iraq.
