Pekanbaru: More than 40 helicopters dropped nearly 240 million litres (63 million gallons) of water and 160 tons of salt for cloud seeding as part of the firefighting efforts to expire forest fires in Indonesia, country's Disaster Mitigation Agency said on Saturday.
Indonesia has sealed off 30 companies amid a row with Malaysia over forest fires that are spreading a thick, noxious haze around southeastern Asia.
"Right now there are a lot of clouds in Riau that allow us to make artificial rain. We will produce artificial rain in three locations, Singkil, Bengkalis, and Siak and make significant rain," said Bonar Hutagaol, an expert from the Indonesian Disaster Management Agency.
The plantation companies, including a Singapore-based company and four firms affiliated with Malaysian corporate groups, are under scrutiny and waiting for decisions on possible punishment, said Sugeng Riyanto, the law enforcement director at Indonesia's Forestry and Environment Ministry.
