Number of ceasefire violations in Donbas remains unacceptably high. May was overshadowed with the highest toll of casualties among Ukrainian servicemen since August 2015.
Embassy of Ukraine in the USA shared on Facebook:
'Over the past month the combined Russian-separatist forces have been persistently violating arrangements on full and comprehensive ceasefire as well as infringing all their commitments under the Minsk Agreements.
May was overshadowed with the highest toll of casualties among Ukrainian servicemen since August 2015. 28 soldiers were killed and 96 were wounded.
Over the last 24 hours 7 Ukrainian servicemen were wounded. In addition to shellings and provocations, Russian-separatist forces intensified their subversive activities, attacking Ukrainian positions and mining the roads.
On the night of 29 May 2016, in militant-controlled village of Mineralne (Donetsk region) an OSCE SMM UAV spotted two 152 mm caliber howitzers 'Akatsiya', firing in the direction of Avdiyivka and hitting close to the location of the monitors. The SMM also continues reporting heavy jamming of its UAVs over the occupied territories.
The uncontrolled border remains a critical impediment to the de-escalation as Russia continues sending its weaponry, regular troops and mercenaries to Donbas. On 30 May 2016, Ukrainian servicemen, fighting back an attack by terrorist subversive group, seized a modern infantry flame-thrower MRO-A, used by the Russian Armed Forces since 2003. On 27 May – 3 June 2016, Russia supplied through the uncontrolled sections of the Ukrainian state border to Donbas nearly 2500 tons of fuel, more than 160 tons of ammunition, 9 MLRS 'Grad', 2 self-propelled artillery systems 'Akatsiya', 36 'T-72' tanks and 6 armored vehicles.
Establishing a sustainable ceasefire and comprehensive security remains a basic precondition for progress on other aspects of the Minsk agreements.
Ukraine urges Russia to respect its commitments under international law, to stop its aggression against Ukraine and reverse the illegal occupation of the Autonomous Republic of Crimea along with the city of Sevastopol.'
At a summit in Minsk on 11 February 2015, the leaders of Ukraine, Russia, France, and Germany agreed to a package of measures to alleviate the ongoing war in the Donbass region of Ukraine.
The talks that led to the deal, overseen by the Organization for Security and Co-operation in Europe (OSCE), were organised in response to the collapse of the Minsk Protocol ceasefire in January–February 2015.
Some of the measures agreed to were an OSCE-observed unconditional ceasefire from 15 February, withdrawal of heavy weapons from the front line, release of prisoners of war, and constitutional reform in Ukraine.
US State Department spokeswoman Jen Psaki said on 13 February that the Russian Armed Forces had actively deployed around Debaltseve to assist the separatists in forcing out Ukrainian troops prior to the 15 February start of the ceasefire. Russia denied this, and Russian government spokesman Dmitry Peskov said that Russia could not assist in the implementation of Minsk II because it was 'not a participant' in the conflict.
