Large rival marches have taken place in Moscow over Kremlin-backed plans for Ukraine’s province of Crimea to break away and merge with Russia. More than 10,000 people turned out Saturday for a rally in the center of the city held to oppose what many demonstrators described as Russia’s invasion of the Crimean Peninsula. In a nearby location, a similar sized crowd voiced its support for Crimea’s ethnic Russian majority, who Moscow insists is at threat from an aggressively nationalist leadership now running Ukraine.
