Malaysia's Firefly cancels Singapore flights as Indonesian haze worsens

Firefly, a Malaysian airline, has cancelled flights to Singapore due to severe haze from Indonesian forest fires, which have made Singapore and Kuala Lumpur the world's most polluted cities. The cancellation highlights the cross-border impact of the fires, which are likely an annual occurrence but this year's severity is notable. The situation underscores regional environmental and health risks, with potential economic disruptions to travel and trade.
