US Secretary of State Mike Pompeo will not visit Ukraine on 3 January.
"Secretary Pompeo must postpone his visit to Ukraine, Belarus, Kazakhstan, Uzbekistan, and Cyprus due to the need for the Secretary to be in Washington, D.C., to continue monitoring the ongoing situation in Iraq and ensure the safety and security of Americans in the Middle East," the US Department of State said on its website.
It added that Secretary Pompeo’s trip would be "rescheduled in the near future".
According to some media reports, Pompeo planned to visit Ukraine in November but eventually got cancelled.
