A ninth French national has died after a crash involving a Greek F-16 fighter jet at a Spanish military base, officials say, reports the BBC.
The airman suffered serious burns in the crash and died on Tuesday at a Madrid hospital, Spain's defence ministry announced.
It brings the death toll from Monday's accident to 11, including the pilots.
Spanish investigators are trying to find out what caused the crash at Los Llanos air base in Albacete.
Defence ministry officials have said that the F-16 "lost power" after take-off from the base, which lies 260km (160 miles) south-east of Madrid.
In Greece, the defence ministry announced a three-day period of mourning beginning on Tuesday to mark the deaths of the Greek pilots.
The plane came down about 1,000ft (305m) from the runway.
Local media reports said one of the two Greek pilots had performed an incorrect manoeuvre, though this has not been confirmed.
