Ukrainians carrying their country's flags stage a protest at the Chongar check point blocking the entrance to Crimea on March 7, 2014. Two buses carrying OSCE observers trying to enter Crimea turned back Friday after being blocked by armed men at a checkpoint, an AFP reporter said. Two sources within the mission said the team of 47 military and civilian observers was returning to the Ukrainian city of Kherson where they had spent the night after being similarly blocked on Thursday.
