Fighting has escalated in Eastern Ukraine ahead of an international summit aimed at ending the conflict.

At least two dozen people have been killed over the past 24 hours.

The leaders of Russia, Ukraine, Germany and France will meet in Belarus to discuss plans for peace - which includes greater autonomy for the pro-Russian East.

Over five-thousand people have been killed since last April - and the West has warned Russia's Vladimir Putin to accept peace or face further sanctions.

Channel 4's Chief News Correspondent Alex Thompson says any deal will see a lot of land come under Moscow's control.
