The US is to reopen its embassy in Ukraine after America Secretary of State Antony Blinken pledged more support to the war-torn country.
The top diplomat, along with defence chief Lloyd Austin, secretly visited Kyiv over the weekend, meeting President Volodymyr Zelensky.
The two secretarys said the fact they were able to travel to Ukraine's capital was proof of its determination to force Moscow to abandon an assault on the capital last month.
