Rabat has not held a Karate 1-Premier League competition since 2019, with the event having been canceled each of the past two years due to the global health crisis.
Morocco has reported a sharp increase in coronavirus cases since late December.
The country has largely closed its borders in response to the emergence of the Omicron variant COVID-19, which is more transmissible, and a nationwide state of health emergency is in place until at least the end of January.
The World Karate Federation is not alone in seeing events in Morocco disrupted, with the International Shooting Sport Federation set to cancel next month’s Shotgun World Cup and the African Men’s Handball Championship delayed by five months, although a political dispute was the main reason.
The postponement of karate means Rabat must now stage the third event of the Karate 1-Premier League season, following competitions in Fujairah in the United Arab Emirates and Lisbon, the Portuguese capital.
Baku in Azerbaijan and the Russian metropolis of Moscow are set to host stages after Rabat, insidethegames.biz reported.
