Serbian President cancels visit to Russia due to discomfort, and had promised to attend the parade in Moscow.

Fico and Vucic suddenly "felt unwell" and canceled all important events, although both intended to go to Moscow for the parade.

The President of Serbia even cut short his visit to the United States due to "health issues," leaving before meeting with Trump to shorten his work schedule. Previously, he had stated that he would not decline the visit to Moscow because he had promised Putin.

However, Slovak Prime Minister Fico was unable to attend due to "falling ill" ahead of Slovakia's May Day celebrations.
