Ukraine under threat of 'full-scale war' with Russia: Poroshenko

Russia has sharply increased its military presence on the border with Ukraine, Ukrainian President Petro Poroshenko said on television on Tuesday, warning of the threat of "full-scale war."
"The number of (Russian) tanks at bases located along our border has tripled," Poroshenko said in an interview, adding that "the number of units that have been deployed along our border -- what's more, along its full length -- has grown dramatically."
