Six of more than 30 people seized at an Iraqi Olympic Committee meeting were released in Baghdad on Sunday, while a British soldier was killed during a raid in southern Iraq.
The six hostages were left blindfolded and unharmed in the capital's Baladiyat neighborhood, Iraq's Sport Journalist Union said. There was no word on the other hostages, including the Olympic National Committee chairman, Ahmed al-Hijiya.
A former member of Iraq's Olympic committee, Nashat Mahir al-Salman, 75, was the first abductee dropped in the neighborhood, followed hours later by Baghdad soccer coach Ahmed Subhi and four security guards, the sports union said.
The victims were seized Saturday in a daylight attack in the heart of Baghdad. Gunmen blindfolded and handcuffed participants and bodyguards, hustled them into about a dozen vehicles and sped away. The bodies of two bodyguards were found dumped on a street.
The International Olympic Committee in Geneva condemned "these acts against the sport community" and called for the immediate release of the hostages.

Four policemen were killed in the attack, according to police officials.
The British soldier was killed during an operation in Basra province to capture "those associated with terrorist activities," the British Defense Ministry said. It was the first British death by hostile fire in seven weeks. Another soldier was wounded.

Two suspects were arrested after the exchange of fire.
