BAGHDAD, Iraq (CNN) -- The bodies of two missing U.S. soldiers were found in the wreckage of their helicopter, which crashed in Anbar province this week, ending a three-day search, a U.S. military spokeswoman said Friday.

Four other crew members who were onboard the U.S. Army Blackhawk helicopter when it went down were found soon after the crash and are in stable condition.

An investigation into the incident found no "enemy action" was involved, the spokeswoman said.

The UH-60 helicopter from the 82nd Aviation Ambulance Company was flying in support of the 3rd Marine Aircraft Wing.

U.N. mission extended

The U.N. Security Council on Friday voted to extend the world body's mission in Iraq by a year.

U.N. Secretary-General Kofi Annan presented the extension to the council, saying Iraq "continued to face formidable political, security and economic challenges" and still relies on the support of the international community.

The decision followed a plea by Iraq's foreign minister for continued U.N. support for the country's shattered physical and economic infrastructure.

The U.N. Assistance Mission for Iraq has helped Iraq's government draft a constitution, reform its legal and judicial systems, provide social and humanitarian services and promote human rights.

Sectarian violence and terrorist attacks in Iraq have risen to unprecedented levels over the past few months.

On Thursday a suicide bomber detonated himself at a police checkpoint near a holy shrine in Najaf, killing 35 people and wounding 122 others, Iraq's Ministry of Defense said. (Full story)
