Ukrainian and Russian delegates have had to be separated after a scuffle during a meeting of Black Sea countries in the Turkish capital Ankara. Oleksandr Marikovski, a Ukrainian member of parliament, landed several blows to the head of a Russian official after his Ukrainian flag was ripped from his hands during a summit at the Turkish parliament building on Thursday. A video posted on Marikovski's Facebook page shows him waving the flag behind Russian delegate Ola Timofeeva as she records a video on her phone. A man approaches, grabs the flag and is chased by Marikovski.
