A US reporter based in Moscow, who was last seen near the war-torn republic of Chechnya, has been missing for three days, the US embassy said in a statement on Wednesday. "We can confirm that a US citizen reporter who lives in Russia has been reported missing since Sunday, February 8, in the area near Mozdok, North Ossetia [which borders Chechnya]," the embassy said, without identifying the journalist. Moscow police told AFP that Rebecca Santana of Cox Newspapers has been missing from Moscow since Sunday and they had launched a missing person's investigation.
