There's quite a good summary on the BBC, along with a condemnation from the Irqi Kurds. The UK has tweeted a mild rebuke 'to both sides', but as anyone here can imagine, U.S. and UK need Turkish cooperation to prosecute an effective campaign against ışıd. once again, Turkey needs to decide whether it wants to be a Western or Islamic country. It can't be both...at least not whilst Erdoğan has a controlling influence in domestic politics...the formation of a government (or fresh elections) within the next month will see some rather mendacious behaviour - with his AKP party attacking the Kurdish-friendly and liberal HDP By accusing it of siding with the PKK.
