MOSCOW — Some of the Russian children caught in limbo by their country’s ban on adoptions by Americans have left for the United States with their new parents, the US Embassy in Moscow said Wednesday.

The confirmation from press attaché Joseph Kruzich was the first official word that any of the 46 children had been allowed to leave Russia. Kruzich did not say how many of the children had already left, but it was clear that all of those adoptions could now go forward, bringing huge relief to the children’s would-be parents in America.
