The 28-year-old finished fourth in the T42 high jump at the Rio 2016 Olympics, having missed out on London 2012 due to a doping ban.

Kumar has also earned gold medals at the 2014 and 2018 Asian Para Games and silver medals at the 2017 and 2019 World Para Athletics Championships during his career. 

He was based in Ukraine to train with his coach Evgeny Nikitin when restrictive measures were put in place due to the coronavirus pandemic. 

Ukraine imposed restrictions on April 6, while India introduced a nationwide lockdown on March 24, making it difficult to return to the country. 

There have been more than 2.2 million cases of coronavirus worldwide, resulting in more than 156,000 deaths. 

"I have told Sports Authority of India officials not to pay my coach as there has been no training this month," Kumar said, as reported by Times of India.

"But the situation is getting worse here and I would like to return to India at the earliest.

"I got in touch with the embassy officials today and they have told me they will keep me in the loop."

Kumar also spoke of his disappointment regarding the postponement of the Tokyo 2020 Paralympic Games, which have been rescheduled to August 24 to September 5 2021 due to the pandemic.

"I was devastated to hear the news about the postponement of the Olympics and Paralympics," he said.

"I toiled hard here for the last three years with just the big event in front of me and suddenly it was not there. 

"The time, effort and money that has gone into the preparations is so much that it is going to be doubly hard to continue this for another 15 months.

"It was like stopping 100 metres away from the summit of Mount Everest."

Earlier this month, Kumar was involved in a 40-person video conference with Indian Prime Minister Narendra Modi to discuss ways to combat the pandemic.

He highlighted water sanitisation as one of the key issues his home nation is facing.
