Russia's Emergency Situations Ministry says Russia has delivered what it says is a third shipment of aid to the rebel-controlled eastern Ukrainian city of Donetsk.
Spokesman Aleksandr Drobyshevsky was quoted as saying on September 20 that the "convoy has arrived in Donetsk and is being unloaded."
Russian news agencies reported the convoy of some 200 vehicles was carrying food, generators, medicines, and bottled water.
According to Russian media, Moscow "several times" invited Ukrainian authorities and the International Committee of the Red Cross to inspect the cargo at the border, "but they declined without providing any reasons."
There has been no confirmation yet from Ukrainian or independent sources about the Russian vehicles crossing the border or reaching Donetsk.
The first Russian humanitarian convoy crossed into Ukraine in late August.
Ukrainian authorities said they had not granted the Russians permission to enter Ukraine and called the convoy's advance across the border a "direct invasion."
The second convoy crossed into Ukraine on September 13.
