Obama arrives in Estonia for talks wit Baltic leaders

US President Barack Obama is due to hold talks on the Ukraine crisis in Talinn Wednesday with the presidents of Estonia, Latvia and Lithuania. He next attends a NATO summit taking place in Brussels Thursday and Friday, which is expected to endorse plans to set up a rapid crisis response force against Russian aggression. Moscow reacted Tuesday with an announcement of plans to revise its military doctrine in response to “NATO infrastructure moving closer to Russian borders.”
