US Secretary of State Antony Blinken said during an unannounced trip to Kyiv on Sunday that US diplomats would return to Ukraine this week, a senior State Department official said, characterizing the move as a strong message of solidarity from the United States, writes CNN.

Blinken and Defense Secretary Lloyd Austin traveled to the Ukrainian capital, where they met with Ukrainian President Volodymyr Zelensky and other Ukrainian officials, making them the highest-level US officials to have traveled to the country since the Russian invasion began in late February.

While in Kyiv, Blinken and Austin met with Zelensky, Foreign Minister Dmytro Kuleba, Defense Minister Oleksiy Reznikov and Interior Minister Denys Monastrysky for an extended, roughly 90-minute bilateral meeting, the senior State Department official said.
