But local media report that senior military officers were on board.
They reportedly included General Francis Ogolla, the president’s chief military adviser and head of the Kenya Defense Forces (KDF).
The BBC has not been able to verify these reports.
According to reports, the helicopter crashed in Kenya’s Rift Valley and caught fire.
Five people aboard the helicopter were killed, while three others survived, the reports said.
Rescue and recovery teams have been sent to the accident site.
In a message on XKenyan government spokesman Isaac Mwaura urged Kenyans to “remain calm and avoid any speculation at this critical moment.”
“An official announcement about the military plane crash will be issued soon,” he said.
