Fires are again shrouding parts of Indonesia’s Sumatra in thick smog, forcing the cancellation of flights two months after forest fires on the island ignited Southeast Asia’s worst haze crisis in years.
Hundreds of fire hotspots have been detected, according to the national disaster mitigation agency.
Flights to and from Pekanbaru, the capital of Riau province, have been disrupted.
In June, haze choked Malaysia and Singapore, prompting Indonesian president Susilo Bambang Yudhoyono to apologise to his neighbours.
The latest fires have not affected Malaysia or Singapore, as winds have carried smoke in another direction.
The fires have been largely blamed on palm oil firms using the illegal but cheap method of burning vast tracts of rainforest to clear them for planting.
