Smoke on the island
Pollution reached “extremely hazardous” levels in several districts of the island’s central eastern province of Riau, said Sutopo Nugroho, spokesman for the National Disaster Management Agency.
“The number of people who have become ill continues to increase,” he said.
Around 2,500 firefighters and soldiers were deployed while aircraft dropped water on the forest fires, he said.
“Scattered blazes and lack of water are hampering efforts.”
The smog has also disrupted flights to and from Sultan Syarif Kasim airport in Pekanbaru, with dozens of cancellations since Sunday, officials said.
Smoke from forest fires on Sumatra is an annual dry season hazard that often affects neighboring Malaysia, Singapore and Thailand.
