Censor.NET reports citing the statement by the press service of the Ministry of Foreign Affairs of Ukraine.
The satatement reads: "The Delegation of Ukraine reiterates the importance of substantial and broad OSCE monitoring on the Russian side of the Ukrainian-Russian border in sections adjacent to the certain areas of the Donetsk and Luhansk regions.
"Having signed the Minsk Protocol of Sept. 5, 2014, all signatories including the Russian Federation undertook commitments to ensure permanent monitoring of the Ukrainian-Russian state border and its verification by the OSCE with the formation of a security zone in the border areas of Ukraine and the Russian Federation.
"Expanding the mandate of the OSCE Monitoring Mission at the Russian Gukovo and Donetsk border crossing points to all sections of the border adjacent to certain areas of the Donetsk and Luhansk regions is critical for sustainable de-escalation and peaceful settlement of the situation in the Donbas.
"We regret that the Russian Federation has again objected to the expansion of the mandate of the OSCE Monitoring Mission at the Russian Gukovo and Donetsk border crossing points to all sections of the border that are temporarily beyond control of the Ukrainian authorities.
"Such persistent reluctance on the part of Russia can only be attributed to its unchanged intention to continue intervention in Ukraine's Donbas, including by sending heavy weapons, military equipment, regular troops, militants and mercenaries, funding the terrorist activities in the territory of Ukraine. As it has repeatedly been emphasized in the formal communications of the Ministry of Foreign Affairs of Ukraine to the Ministry of Foreign Affairs of the Russian Federation, these actions by Russia constitute internationally wrongful acts, which entail international responsibility. We continue urging Russia to immediately cease these acts.
"In this regard it is noteworthy, in particular, that for months Russia has been unable to provide explanations on the presence of sophisticated modern Russian weaponry in the occupied areas of Donbas including TOS-1 Buratino and radio-electronic jamming system R-330 Zhytel, which are used exclusively by the Russian Armed Forces.
"We urge the Russian Federation to demonstrate its full commitment to the implementation of the Minsk agreements in good faith and allow proper and comprehensive permanent monitoring by the OSCE on the Russian side of the Ukrainian-Russian state border adjacent to the areas in Donbas which are currently not controlled by the Ukrainian government."
