Ukraine crisis: Putin visit to Crimea angers US and EU

The US and EU have condemned President Vladimir Putin's first visit to Crimea since Russia annexed the peninsula from Ukraine in March.
The US state department said the trip was "provocative and unnecessary". The Kiev government called it a "gross violation of Ukraine's sovereignty".
Mr Putin praised Crimea for joining Russia, as he marked the Soviet victory over the Nazis in World War Two.
As he visited, there were deadly new clashes in south-eastern Ukraine.
Ukraine's Interior Minister Arsen Avakov said at least 20 pro-Russian activists and a Ukrainian security officer died in the clashes in the port of Mariupol.
The government said there was a gun battle when pro-Russian activists tried to storm a police HQ.
However, some local witnesses accused the security forces of opening fire on unarmed protesters who had entered the building. Local officials put the casualties at seven dead and 39 injured.
