Oleg Nikolenko

, a representative of the Ministry of Foreign Affairs of Ukraine, announced this on the official Twitter page

.

He stated that Russia should bear responsibility for attempts to change the internationally recognized borders of Ukraine in violation of the UN Charter.

Referendums on leaving Ukraine and joining Russia began in the so-called "LPR" and "DPR" and in parts of the Kherson and Zaporizhia regions on September 23 and are scheduled to last for five days.

Representatives of the international media and observers of international structures are absent from the voting areas.

Both Ukraine and the international community declared that they do not recognize their results.

The media reports that the so-called referendums in Ukrainian regions are held with mass violations of the regulations, outside the voting premises, without preserving the secrecy of the vote and under the control of armed men.

Many experts fear that the results of the so-called referendums will be falsified, and immediately after their end - on September 29-30 - Russia may declare these regions part of its territory, which will allow it to declare martial law in the country and increase military aggression up to the possibility of using nuclear weapons.
