UNITED NATIONS, March 1 (Reuters) - The U.N. Security Council will hold an urgent meeting on the crisis in Ukraine on Saturday after Russia announced plans to send armed forces into the autonomous Crimea region of the former Soviet republic, council delegations said.
A diplomat from Luxembourg, president of the 15-nation council this month, said the meeting would take place at 2:00 p.m. EST (1900 GMT) and was being convened at the request of Britain.
The council met on Friday to discuss the crisis in Ukraine's Crimea region but took no formal action, as expected. The meeting highlighted the deep divisions between the United States and other Western nations and Russia, which has a major Black Sea naval base in the Crimea.
At Friday's session, Ukraine accused Russia of illegal military incursions onto Ukrainian territory, while U.S. and European delegations warned Moscow to withdraw any new military forces deployed in neighboring Ukraine. Russia, however, said any military movements by Russian forces there were in compliance with its agreement with Kiev on maintaining its naval base there.
Russia is a veto-wielding permanent member of the Security Council and, therefore, able to block any actions proposed by its members. (Reporting by Louis Charbonneau; +1-646-591-5178)
