British officials are investigating whether enemy fire or an accident was to blame for the crash of an RAF Hercules transport aircraft in Iraq yesterday.
Britain's Defence Secretary, Geoff Hoon, said ten military personnel are missing, believed dead, after the crash 40km northwest of Baghdad.
The Arab television channel Al-Jazeera has aired a video which was reported to have come from insurgents who claim they shot down the plane.
It shows two rockets being fired, then cuts to plane wreckage on the ground.
Suspected insurgents detained
In a separate development, the Iraqi government has said it detained more than 200 suspected insurgents, including four Arab foreigners, in the run up to yesterday's election.
The Interior Ministry also said four suspected insurgents were killed in shootouts on polling day, in which the turnout is now estimated to have been between 60-75%.
Iraq's interim Prime Minister Iyad Allawi has meanwhile urged national unity.
An official said although no accurate figure was yet available, the turnout had been better than expected and a majority of voters appeared to have taken part in the poll in most parts of the country.
However, he acknowledged that the number of voters was low in Baghdad and in other regions where Sunni Muslim opposition to the election was concentrated.
The counting of votes is underway with preliminary results expected in about six days and a full result not due for ten days.
The candidates elected will form a transitional administration that will appoint a president and draw up a new constitution for the country.
It is planned that this will be put to the people in a referendum and that new elections for a full government will be held in December.
Al-Qaeda's group in Iraq, however, has vowed to continue its war, and described the elections as an 'American game'.
