The Japanese government may ask parliament to authorize a two-year extension of its air force mission to Iraq because of continued unrest across much of the country, a news report said Friday. Tokyo has been airlifting UN and coalition personnel and supplies into Baghdad and other Iraqi cities from nearby Kuwait since earlier this year as part of efforts to support reconstruction of Iraq. The current mission, authorized under a special law, runs through July 31 next year. The government may submit a bill to parliament next year that would extend that mission through July 2009, the Yomiuri Shimbun, a mass-circulation daily, said Friday on its online edition. Officials at the Cabinet Office and Foreign Ministry did not return calls seeking comment Friday morning.
