Ukraine PM: Keep sanctions on Russia until territory regained

Ukraine's prime minister has urged the world not to lift sanctions against Russia until his country regains control over its entire territory, including Crimea.

A "significant" number of Russian troops have now withdrawn from Ukraine, a Nato spokesman said.

It comes after the two countries agreed a ceasefire deal earlier this month.
