Dozens of Sri Lankan students at a school in a suburb of Colombo, were hospitalised on Wednesday after they were exposed to a toxic vapour, the police said.
The students were sent to the preliminary care unit of the local hospital after they fainted.
The police said that some discarded rubber products had been burned in an adjoining land, with heavy smoke filtering into several classrooms.
