In a statement, RwandAir said the incident was "as a result of bad weather".

All passengers and flight crew disembarked safely with no reported injuries, it added.

The aviation regulator said an alternate runway is operational for small and light aircraft.

"All efforts are underway to remove the aircraft from the runway strip so that the main runway can return to full use," it said.

Uganda's main newspaper, Daily Monitor, reports that 20 of the 60 passengers on board are scheduled to attend the birthday party of President Yoweri Museveni's son Muhoozi Kainerugaba.

It reports that Gen Kainerugaba's 48th birthday party is set for Sunday.

Gen Kainerugaba, who is also the commander of land forces, tweeted on Monday that former Miss Rwanda will be among the guests at the event.
