An Air France Boeing 777-200, registration F-GSPG performing flight AF-953 from Malabo (Equatorial Guinea) to Douala (Cameroon) with 37 people on board, was en route to Douala maintaining FL090 when the crew requested and was cleared to deviate north of the assigned route due to thunderstorms. Later, while turning right towards Douala the EGPWS of the aircraft issued a terrain warning and called "PULL UP!" which the crew complied with climbing the aircraft to FL130, where the EGPWS stopped the warnings. The aircraft subsequently continued for a safe landing in Douala.
The French BEA reported in their weekly bulletin that the occurrence was rated a serious incident, the French BEA is investigating the serious incident.
