The US Embassy on Wednesday confirmed that two American women have been hospitalized in Moscow for possible thallium poisoning. The spokesman identified the women as Marina Kovalevsky and her daughter, Yana, but did not give their ages or say where in the United States they were from. He said they were hoping to return home soon, but it was not immediately clear when they might be able to do so. The hospital where they have been treated since falling ill on Feb. 24 said Wednesday morning that they were in moderately serious condition. Russian news reports say both women are Soviet-born and emigrated to the United States in 1989, and that they have visited Russia repeatedly since then. The reports say they arrived in Moscow in mid-February to attend a wedding.
