A Russian aid convoy of 280 trucks en route to Ukraine could be an attempt by Moscow to install a permanent presence in the country, according to France's foreign minister Laurent Fabius.
He told France Info radio: "We must be extremely careful because this could be a cover for the Russians to install themselves near Lugansk and Donetsk and put us before a done deed."
He added: "This (convoy) is only possible, only justifiable, if the Red Cross authorises it."
