US President Barack Obama Arrives in Estonia For talks on Russia and Ukraine crisis 

US President Barack Obama has arrived in Estonia for talks on Russia and the Ukraine crisis with Baltic leaders.

He is due to hold talks with the presidents of Estonia, Latvia and Lithuania.  

Reports say the three states, which joined Nato in 2004, are worried about Russia's intervention in Ukraine.

Later in the week President Obama will attend a Nato summit that is expected to back plans for a rapid-response force that could be dispatched within 48 hours. 

Nato recently announced plans to set up the force to protect Eastern European members against possible Russian aggression.
