Ukraine president hits out over 'Russian tanks'

KIEV: Ukraine's new president told his Russian counterpart the reported crossing of three tanks into his country's separatist east was "unacceptable", as the pair held what Kiev called "substantive and extended" telephone talks.

President Petro Poroshenko also discussed his plans to defuse the crisis in the east of the country as he held what are thought to be his first telephone talks with Russia's Vladimir Putin since he was sworn in at the weekend.
