Thousands of Indonesians prayed for rain in haze-hit towns on the islands of Sumatra and Borneo on Wednesday, as forest fires raged at the height of the dry season.

Axar.az reports citing Reuters that fires have burnt through parts of Sumatra and Borneo island for more than a month and the government has sent 9,000 military, police and disaster agency personnel to fight the flames.

Indonesia’s neighbors regularly complain about smog caused by its forest blazes, which are often started to clear land for palm oil and pulp plantations.

But Indonesia said this week it was not to blame and fires had been spotted by satellites in several neighboring countries.
