Two planes were Thursday grounded at the Wilson Airport over claims of engaging in illegal activities.
The planes were headed for Somalia and it is said they were carrying passengers instead of cargo.
Another passenger plane was carrying tones of miraa destined for Somalia when authorities declared they would not leave.
Although he did not name the affected airlines, Transport Cabinet Secretary James Macharia warned passenger airlines licensed to carry passengers only not to also operate as cargo airlines which is contrary to the license conditions.
Macharia who spoke at the airport urged agencies charged with licensing the airlines to take firm action on airlines contravening regulations.
