Ukraine: G8 preparations on hold over Russian military in Crimea

The leaders of the world's top industrialised nations have jointly condemned Russia for what they say is its clear violation of Ukraine's sovereignty and have put preparations for June's G8 summit on hold.

The moves come as Russian military forces continue to strengthen their grip on the Crimean peninsula.

Meanwhile, European Union foreign ministers are due to meet in emergency session in Brussels later.
