Kyiv has warned that an interruption of US weapons shipments will encourage Russia to prolong the war in Ukraine, now in its fourth year, BBC reported.

On Tuesday the White House said it had cut off some weapons deliveries to Ukraine.

The decision was taken "to put America's interests first" following a defence department review of US "military support and assistance to other countries", White House spokesperson Anna Kelly said, according to BBC.

Ukrainian President Volodymyr Zelensky said the two countries were now "clarifying all the details on supplies", while the foreign ministry warned any delays "would only encourage the aggressor to continue war and terror, rather than seek peace".
