1. The clash between Russia and the West is intensifying.

Russia will expel 150 diplomats, including 60 Americans, in retaliation for Western measures designed to punish Moscow for its alleged role in a nerve-agent attack on a former spy in Britain. Russia denies any involvement.

Foreign Minister Sergey Lavrov, above, summoned the American ambassador, Jon Huntsman, to his office to give him the news. The Americans were given until April 5 to leave the country.

The daughter of the spy, who was also poisoned, is showing improvement as she recovers in a British hospital.
