Norway's prime minister says a group of northern European nations and the UK support a US proposal for an unconditional 30-day ceasefire between Russia and Ukraine. "We need a ceasefire, an unconditional ceasefire, first," Norwegian Prime Minister Jonas Gahr Store tells reporters on the sidelines of a meeting of the Joint Expeditionary Force (JEF) coalition in Oslo. "That needs to be monitored and respected before you can move into the negotiations on the big issues to reach a lasting peace," he adds. SOUNDBITE
