HAVANA, May 27 (Xinhua) -- Cuba's Institute of Forensic Medicine (IFM) has identified the remains of all the victims of the plane crash which took place on May 18 near Havana's Jose Marti International Airport, the daily Juventud Rebelde reported on Sunday.

The Institute informed Saturday night the families of the nine remaining unidentified victims that the bodies had been recognized, concluding the exhaustive identification process of the 110 immediate victims of the tragedy.

Sergio Rabell, director of the IFM, stressed that the "work of the experts has been intense, since the victims had multiple injuries and many of them were burned."

Rabell said that the bodies of the 11 foreigners had DNA tests, for the Cuban victims, DNA tests were carried out only when other markers, such as tattoos or scars, could not be found.

On Friday, May 18, a Boeing 737 flying between Havana and the eastern city of Holguin city crashed minutes after take-off with 113 people on board.

These included 102 Cuban passengers, five foreign passengers and six Mexican crew.

The aircraft belonged to the Mexican company Damojh and had been leased by the island's national airline, Cubana de Aviacion.

Four Cubans survived initially but a male survivor died on the way to the hospital. Two other female survivors died later in intensive care while the final one is in critical condition.

The Cuban government has appointed an official commission to investigate the cause of the crash, led by Jose Armando Daniel Lopez, president of Cuba's Institute of Aeronautics and Civil Aviation.

Lopez said "it could take months to reach credible...conclusions" about the cause.
