A militant group says it has beheaded a man it claims was a senior member of Iraq's armed forces.

The Army of Ansar al-Sunna posted a video of the beheading on its Internet site, Wednesday. The group said the execution was carried out in the northern Iraqi city of Mosul.

Earlier, a Jordanian government spokeswoman said four Jordanian drivers were kidnapped in Iraq, but did not say where they were abducted. She said Jordan will take up the matter with visiting Iraqi Prime Minister Iyad Allawi.

Meanwhile, Iraqi police say a Lebanese-American contractor was kidnapped late Tuesday from his Baghdad home.
