ERBIL: The Iraqi government ruled out talks on possible secession for Kurdish-held northern Iraq on Tuesday and Turkey threatened to choke it off, after a referendum on independence there showed strong support for a split. Initial results of Monday's vote indicated 72 percent of eligible voters had taken part and an overwhelming majority, possibly over 90 percent, had said "yes", Erbil based Rudaw TV said. Final results are expected by Wednesday. Celebrations continued until the early hours of Tuesday in Erbil, capital of the Kurdish region, which was lit by fireworks and adorned with red-white-green flags.
