Colombian officials are questioning a bus driver over the deaths of at least 32 children.
They were killed when the overcrowded bus they were on caught fire.
Colombian President Juan Manuel Santos has called for a national day of mourning. On Sunday night, Santos traveled to the town near the Caribbean coast to pay his respects to the mostly poor families of the victims, interrupting his busy final stretch of campaigning ahead of May 25 elections.
