Kenya Airways said early today it had lost contact with a 737-800 jetliner bound for Nairobi from Douala, Cameroon, with more than 100 people aboard.
"We have no details about what has happened to the aircraft," Kenya Airways Chief Executive Titus Naikuni said.
"The last message from the aircraft was received by the control tower in Douala immediately after takeoff," Kenya Airways said on its website.
The airline said it opened a crisis management center near the Nairobi airport and had no further details.
Calls to Kenya Airways were not immediately returned.
