The president of Iraqi Kurdistan has called on Turkey's Kurds to back a flagging peace process with Ankara, in a show of support for Prime Minister Tayyip Erdogan's bid to overcome a three-decade conflict. Masoud Barzani made the announcement on Saturday during his first visit to Diyarbakir, the main city in Turkey's Kurdish-dominated southeast, in two decades.
