KYIV, May 14 (Reuters) - U.S. Secretary of State Antony Blinken arrived in Kyiv on Tuesday in the first visit to Ukraine by a senior U.S. official since Congress passed a long-delayed $61 billion military aid package for the country last month.
The previously undisclosed trip aims to show U.S. solidarity with Ukraine as it struggles to fend off heavy Russian bombardment on its northeastern border.
Blinken, who arrived in Kyiv by train early on Tuesday morning, hopes to "send a strong signal of reassurance to the Ukrainians who are obviously in a very difficult moment," said a U.S. official who briefed reporters traveling with Blinken on condition of anonymity.
"The Secretary's mission here is really to talk about how our supplemental assistance is going to be executed in a fashion to help shore up their defenses (and) enable them to increasingly take back the initiative on the battlefield," the official said.
