Ukrainian intelligence and data from the OSCE Special Monitoring Mission prove that militants violate the conditions of withdrawing arms from the contact line in Donbas, spokesman of the Ukrainian presidential administration for the anti-terrorist operation in Donbas Oleksandr Motuzianyk said at a briefing in Kyiv on Tuesday.

The SMM OSCE published a report proving that militants violate the conditions of arms withdrawal, in particular an observers' drone registered a concentration of military hardware and arms on territories controlled by the self-proclaimed Donetsk People's Republic in the direction of Mariupol, Motuzianyk said.

In particular, there are two tanks near the village of Bezimenne, 26 tanks and one Strela 10M surface-to-air missile system near the village of Solntseve, three tanks near the village of Michurine, and a Gvozdika self-propelled howitzer near the villages of Petrivske and Zhovten, he said, adding that militants tried to jam the SMM OSCE drone.

"Ukrainian intelligence confirms this information," Motuzianyk said.
