IMO - Putin is pushing for Ukraine to physically stop the convoy, to give him an excuse to intervene overtly with his military.
Lorries from a Russian aid convoy are streaming into Ukraine, without permission, after Russia accused Ukraine of obstructing it.
Russia's foreign ministry said Ukraine had held up the convoy in order to pursue war against rebels in Luhansk, where the aid is destined.
The International Committee of the Red Cross (ICRC) said it was "not part of that convoy in any way".
