A Russian aid convoy will not be allowed to enter Ukrainian territory, according to an aide of the country's president Petro Poroshenko.
Instead, Valery Chaly told Reuters that the cargo will be transferred onto other vehicles by the Red Cross at the border.
He said: "We will not allow any escort by the emergencies ministry of Russia or by the military (onto Ukrainian territory). Everything will be under the control of the Ukrainian side."
Some including French foreign minister Laurent Fabius have said they fear the convoy could be an attempt by Moscow to install a permanent presence in Ukraine.
