A woman believes her sister was aboard a plane which crashed in Nigeria, killing everyone on board.
Jill Chime, from Liverpool, told Radio 5 Live's Up All Night programme her family had seen a passenger list which included the name of her sister, Antonia Attuh.
Ms Chime said another sister had flown to Nigeria to help other family members find Ms Attuh's body, which they believe is in a hospital mortuary.
All 153 passengers died when the Dana Air flight crashed in a neighbourhood about five miles north of Murtala Muhammed International Airport in Lagos, south-west Nigeria, on Sunday.
The plane was coming from the Nigerian capital Abuja when it crashed into a printing works and residential buildings in the busy Iju-Ishaga suburb.
An unknown number of people on the ground were also killed.
The Foreign Office was unable to confirm whether Ms Attuh was aboard but a spokeswoman said: "It is believed that there was a dual British-Nigerian national on board the flight.
"The Foreign Office has been in contact with a member of her family and offered consular assistance."
On Tuesday, the Nigerian government suspended the licence of Dana Air airline as a matter of safety and grounded all of its flights while it investigates the accident.
The Dana Air McDonnell Douglas MD-83's crew radioed the tower at the airport in Lagos shortly before the crash to say they had engine trouble, but the exact cause remains unclear.
