According to Turchynov, the Russian force is equipped with more than 300 tanks, over 1,800 armored combat vehicles, more than 750 artillery systems and rocket launchers, and 360 combat aircraft and attack helicopters.

Earlier it was reported that Russia is intending at the end of this month to send to Ukraine another "humanitarian convoy."

Ukraine claims that the convoys, which are sent into Ukraine without Kyiv’s permission and without being inspected by the Ukrainian authorities, are being used to resupply Russian-backed militants in the areas of Ukraine in which they have seized control from the local authorities.
