LONDON (Reuters) -Ukrainian President Volodymyr Zelenskiy appealed to Britain on Tuesday to do more to help his country battle Russia and punish what he called a "terrorist state", striking a defiant tone that Ukraine would fight on, no matter what the cost.

Addressing Britain's parliament and greeted by a standing ovation in a packed chamber of lawmakers, Zelenskiy documented the Russian invasion day by day, listing the weapons used, the civilians killed and the lack of food and water for many.
