An extremists' group posted a Web video Sunday showing the killings of three Russian embassy workers abducted earlier this month in Iraq. A fourth also was said to have been killed. An accompanying statement by the Mujahedeen Shoura Council, an umbrella organization linking seven insurgent groups in Iraq, said all four Russians had been killed. Russia's Foreign Ministry said it had not yet confirmed the hostages' deaths, according to a report of the Associated Press. The 90-second video, posted on an Islamic Web site that frequently airs messages, showed the beheading of two blindfolded men and the shooting of a third.
