Turkey has just attacked one of the UKs allies in Northern Syria!
Turkish F-16 and F-4 warplanes have bombed Kurdish PKK rebel targets in Hakkari province near the Iraqi border.
Last week Kurdish protests gripped Turkey's Kurdish-majority south-eastern provinces. At least 31 people died in widespread street clashes, as Kurds vented their anger at Turkey's passive policy over Kobane. The army imposed a curfew in some areas. But some of the fighting was reported to be between PKK supporters and Islamist Kurds sympathetic to IS. Inside Syria heavy fighting has been raging in Kobane since mid-September, as Syrian Kurds battle to defend the town against better-armed IS militants.
What happens now?
