Nepal hit by worst wildfires in almost a decade

Nepal is experiencing its worst fire season in almost a decade, officials said Tuesday, as huge blazes rage across the country's forests, engulfing the Himalayan nation in a shroud of brownish haze.

Air quality in the capital Kathmandu was ranked on Tuesday as the worst in the world, according to monitoring site IQAir, with some international flights delayed as thick smoke blanketed the city.
