IRBIL, Iraq (AP) — Iraq's Kurds hope Monday's non-binding referendum on independence marks the start of a peaceful, negotiated break with Baghdad, but it may have instead placed them on a new collision course with Iraq and its neighbors. Iraq's central government rejected the vote long before it was held, and Prime Minister Haider al-Abadi has warned of "follow-up steps to protect the unity of the country." Turkey and Iran have staged military drills on the borders of Iraq's Kurdish region, and Turkish President Recep Tayyip Erdogan has threatened to send in troops.
