HAVANA (CBSNEWS) – The only three survivors of Cuba’s worst aviation disaster in three decades were clinging to life Saturday, a day after their passenger jet crashed in a fireball in Havana’s rural outskirts with 113 people on board.

In the first official death toll provided by authorities, Transportation Minister Adel Yzquierdo Rodriguez said 110 had died including five children. Official website Cubadebate reported, citing Yzquierdo, that a flight recorder from the plane had been located.

Carlos Alberto Martinez, director of Havana’s Calixto Garcia Hospital where the survivors were being treated, said doctors are always hopeful that their patients will recover, but he acknowledged that the three Cuban women were in extremely grave condition.

“We must be conscious that they present severe injuries,” Martinez told a small group of journalists. “They are in a critical state.”

Cuban officials identified the women as Maylen Diaz, 19, of Holguin; Grettel Landrovell, 23, of Havana; and Emiley Sanchez, 39, of Holguin.

Meanwhile relatives of the dead gathered at a morgue in the capital, weeping and embracing each other, as investigators tried to piece together why the aging Boeing 737 went down and erupted in flames shortly after takeoff early Friday afternoon.

Yzquierdo said those on board included 102 Cubans, three tourists, two foreign residents and six crew members, who were from Mexico.

Maite Quesada, a member of the Cuban Council of Churches, announced that 20 pastors from an evangelical church were among the dead. They had spent several days at a meeting in the capital and were returning to their homes and places of worship in the province of Holguin.

Skies were overcast and rainy at the airport at the time of Cuba’s third major air accident since 2010, and state television said the 39-year-old jet veered sharply to the right after departing on a domestic flight to the eastern city of Holguin.

Eyewitness and private salon owner Rocio Martinez said she heard a strange noise and looked up to see the plane with a turbine on fire.

“In flames, here it comes falling toward the ground, and it seems (the pilot) saw it was an area that was too residential and makes a sharp turn,” Martinez said. “To avoid (the houses) … to avoid a tragedy, because there would have been a massacre.”

The screams of high school kids could be heard inside a nearby school as they ran to safety, CBS News’ Manuel Bojorquez reports.

Cuban President Miguel Diaz-Canel said a special commission had been formed to find the cause of the crash. The plane had 104 passengers and six crew members.

State airline Cubana, which operated the flight, has had a generally good safety record but is notorious for delays and cancellations and has taken many of its planes out of service because of maintenance problems in recent months, prompting it to hire charter aircraft from other companies.

Mexican officials said the Boeing 737-201 was built in 1979 and rented by Cubana from Aerolineas Damojh, a small charter company that also goes by the name Global Air.
