A FLEET of drones sprayed water over Bangkok in an effort to tackle surging air pollution amid fears of a public health crisis.
The drones, backed up by planes and trucks, were sent up after the Thai government closed more than 400 schools and advised citizens to stay indoors.
Traffic exhaust, construction works, burning crops and pollution from factories are blamed for the haze.
City governor Asawin Kwanmuang said using drones was not a long-term solution and invited experts and academics to ‘brainstorm’ with him to improve air quality. Critics said the drone plan was ineffective.
