Ukraine tension: President Zelensky hits back at Biden comments
Ukraine's President Volodymyr Zelensky has hit back at comments made by his US counterpart Joe Biden about a "minor incursion" by Russia into his country.
Mr Biden had suggested that a "minor" attack might bring a weaker response from the US and its allies.
But Mr Zelensky tweeted: "There are no minor incursions. Just as there are no minor casualties and little grief from the loss of loved ones."
Russia has some 100,000 troops near the border but denies planning an invasion.
