It gets worse on the Turkish/Kurdish border. 7 Turks killed.

If the Turks are looking for a reason, seven soldiers killed in a rocket attack is as good as any.

Kurdish rebels fired rockets and grenades at a Turkish military outpost Monday, killing seven soldiers in an attack that heightened tension at a time when Ankara has threatened military action against the rebels in northern Iraq.....

Abdul-Rahman al-Chadarchi, a spokesman for the Kurdish rebel group PKK, told The Associated Press by telephone that there had been artillery shelling from Turkey into Iraqi territory at dawn, and that there had been simultaneous shelling from the Turkish and Iranian sides on Sunday night.

I probably should relink to the recent warning from the Turkish army on Friday that came in response to a checkpoint incident.

The Turkish army on Friday warned Kurds in control of neighbouring northern Iraq that Ankara would respond "at the highest level" if its soldiers in the autonomous region are treated badly or harmed.

(On the charge that Iran was shelling, too, I'd like to wait and see a source other than the PKK spokesman, but at this point treat it as a real possibility.)
