Illegal forest fires in Indonesia’s Sumatra islands are causing hazardous smog problems in Singapore.

Earlier this week the pollution standard index reached a record level and local shops are reporting they have sold out of face masks. The Singaporean Prime Minister predicts the smog could last for weeks and has issued an advice to stay indoors and avoid strenuous activity.

Air traffic controllers in Singapore have been told to work with extra caution given the poor visibility.

Travellers to the region are asked to take heed of the situation but there are no official warnings not to travel. Moving forward, travellers should stay close to media updates for awareness.
