Ukraine says it repelled Russian bid to cross border ( www.bbc.com )

Ukraine says it has repelled a Russian armoured attack in the north-eastern Kharkiv region, after Moscow's forces launched an incursion across the border and sought to break through defensive lines. 

Kharkiv regional head Oleh Syniehubov said Russian reconnaissance groups had tried to penetrate the border, adding that "not a single metre has been lost".

"Russia has launched a new wave of counteroffensive operations in the Kharkiv sector," said Ukrainian President Volodymyr Zelensky.

Ukrainian commanders have been expecting a summer offensive for some time, possibly even a bid to capture the regional capital Kharkiv. But officials are adamant Russia does not have the resources to do so.
