**A Shia militant group in Iraq has reportedly posted an internet video showing an abducted man who may be a missing US military contractor.**US defence officials identified the missing contractor as Issa Salomi, last seen on 23 January, AP said.
In the video, the man says he has been abducted by the League of the Righteous, who are demanding the release of militants.
He adds that they want the prosecution of Blackwater security contractors.
Blackwater employees are accused of killing 17 Iraqis in 2007.
He also says the group is demanding the immediate withdrawal of the US military from Iraq.
The US military in Baghdad on Saturday told the Associated Press news agency that Mr Salomi, 60, was missing, but declined to comment further.
