The mayor of Odesssa said on Friday Russian forces could soon surround his southern Ukrainian port city on three fronts. Mayor Gennadiy Trukhanov suggested Russian forces would seek to advance from territories they have occupied in Ukraine’s Mykolaiv region towards Moldova's separatist-controlled Transdniestria region, where Russian troops are based. Such a move could cut Odessa off from the rest of Ukraine. "Also, we think that while this is happening, Russian landing ships could surround us from the sea,"
