“I would appreciate your kind assistance in having this letter and the enclosed statement [on the escalation in Donbas] distributed as a document of the General Assembly under the Agenda item 31 of its 71st Session and of the Security Council,” the letter reads.

In the statement, the Ministry of Foreign Affairs of Ukraine “expresses its strongest protest against the intensification of Russia’s hybrid forces, including with the use of tanks, self-propelled artillery, rocket launchers and mortars.”

“We demand from the Russian Federation an immediate halt to the armed provocations, which are increasing the number of casualties and the destruction of regional infrastructure. Furthermore it must start to fully implement its own commitments under the Minsk agreements,” the Ukrainian diplomats wrote.
