A tram passes a portrait of Andriy Biryukov, a pro-Ukrainian activist killed in clashes on Friday, at his funeral in Odessa May 6, 2014. Pro-Russian rebels shot down a Ukrainian helicopter in fierce fighting near the eastern town of Slaviansk on Monday, and Kiev drafted police special forces to the southwestern port city of Odessa to halt a feared westward spread of rebellion.
