"We're prepared to make sure the rights of all Ukrainians are upheld," Obama says.

16:17 Statement by Nato following meeting under article 4 of the Washington Treaty:

The North Atlantic Council has met at Poland's request to hold consultations within the framework of Article 4 of the Washington Treaty, which states that "the parties will consult whenever, in the opinion of any of them, the territorial integrity, political independence, or security of any of the parties is threatened."

Despite repeated calls by the international community, Russia continues to violate Ukraine's sovereignty and territorial integrity, and to violate its international commitments.

These developments present serious implications for the security and stability of the Euro‑Atlantic area.

Allies stand together in the spirit of strong solidarity in this grave crisis.

We undertake to pursue and intensify our rigorous and on-going assessment of the implications of this crisis for Alliance security, in close coordination and consultation.

We continue to support all constructive efforts for a peaceful solution to the current crisis in accordance with international law. We welcome the ongoing efforts undertaken by the United Nations, the European Union, the OSCE and the Council of Europe.

We will continue to consult with Ukraine within the NATO-Ukraine Commission.

We will engage with Russia in the NATO-Russia Council. We will hold a meeting tomorrow.

"We hold a decent amount of treasury bonds – more than $200 billion – and if the United States dares to freeze accounts of Russian businesses and citizens, we can no longer view America as a reliable partner," Glazyev said.
