NATO Allies expressed their serious concern about the recent sharp escalation of violence in eastern Ukraine.

"Today, NATO Allies discussed the situation in eastern Ukraine. Allies expressed their serious concern about the recent sharp escalation of violence….Russia has a special responsibility to find a political solution. Any attempt by the Russian-backed separatists to take over more of Ukraine's territory would be unacceptable to the international community," reads a press release posted on NATO website on results of the aforementioned meeting.

In a course of the discussion the allies stressed the need for all parties to de-escalate tensions and exercise restraint.

"They underlined that the focus must be on pursuing a solution through diplomatic means. The full implementation of the Minsk agreements is the path to peace," NATO said.

According to the organization, OSCE monitors must be able to do their job safely and without restrictions.

"NATO stands firm in our support for Ukraine's sovereignty and territorial integrity. Allies reaffirmed that an independent, sovereign and stable Ukraine, firmly committed to democracy and the rule of law, is key to security in the Euro-Atlantic area," the document said.

NATO said it would continue to follow the situation very closely.
