Ukraine’s Volodymyr Zelenskiy held new talks with US President Joe Biden after a deal to allow safe passage for civilians in two besieged southeastern cities appeared to collapse, with the government in Kyiv accusing Russian forces of violating the agreement. Biden’s “administration is surging security, humanitarian, and economic assistance to Ukraine and is working closely with Congress to secure additional funding,” he told Zelenskiy on Saturday evening, according to a White House statement cited by Bloomberg.
