Men wearing military uniforms seized Peter Moore, a 36-year-old computer specialist, and his four bodyguards outside the Finance Ministry in a daring daytime raid in May 2007.
The bodies of three of the bodyguards have been handed over to British authorities. Moore was released alive last Wednesday but the fate of the final hostage remains unknown.
The kidnappers had demanded the release of Shi’ite militiamen, including Khazali and his brother Laith al-Khazali, in exchange for the British hostages. Laith al-Khazali was released in June.
In August, the group agreed to lay down its weapons and join the political process in return for Prime Minister Nouri al-Maliki’s promise to seek the freedom of the remaining detainees in US custody.
Qais al-Khazali’s transfer from US to Iraqi custody coincided with Moore’s release. But US officials insisted the events were unconnected, saying the transfer was part of a wider program spelled out in a US-Iraq security deal to free or transfer detainees from US to Iraqi government custody.
Iraqi officials involved in the negotiations said the militant group did not release Moore until it got confirmation its leader was transferred to Iraqi custody.
