Ukraine military says Russian tanks, missile systems cross border

KIEV (Reuters) - Ukraine's military said on Friday more than 20 Russian tanks, 10 missile systems and bus-loads of fighters had crossed Ukraine's border and headed towards Novoazovsk, a rebel-held town east of the strategic southeastern port city of Mariupol.

"In recent days, despite the Minsk (ceasefire) agreement, military equipment and ammunition has been tracked crossing from Russia into Ukraine," military spokesman Andriy Lysenko said in a televised briefing.
