“The Church in Colombia is praying for the parents who are mourning the tragic deaths of their children,” Cardinal Salazar said via Twitter.
According to Colombian media, the 32 children were returning from a Pentecostal revival meeting on May 18, when the bus that was carrying them burst into flames near the town of Fundacion in northern Colombia.
Authorities are working to determine the cause of the fire.
The mayor of Fundacion, Luz Stella Duran, told Caracol Radio on May 19 that it could take coroners up to four days to identify the remains of each of the children.
She said the bodies of the children have been taken to Barranquilla to be identified and that the mayor's office is providing transportation to the city for their families.
Cardinal Ruben Salazar of Bogota, president of the Bishops' Conference of Colombia, offered his prayers and condolences for the families of 32 children who died in a bus that caught fire.
