Flames burning a palm oil plantation light up the area as the moon shines in the sky in haze-hit Bangko Pusako district in Rokan Hilir, Indonesia's Riau province, June 22, 2013. Air quality in Singapore improved significantly to "moderate" pollution levels on Saturday, as Indonesian planes waterbombed raging forest fires and investigators scrambled to determine the cause of one of Southeast Asia's worst air pollution crises.
