According to CNBC, Singapore is grappling with severe haze as smoke from wildfires in Indonesia drifts into the city-state, and Prime Minister Lawrence Wong said the government is looking into companies potentially responsible for the fires. Wong said authorities could take legal action under Singapore's Transboundary Haze Pollution Act where warranted and is also exploring joint action with other countries. Air quality remained unhealthy on Thursday, and government data showed Singapore first deteriorated to unhealthy levels on Sept. 4, the first time in nearly three years.

The haze has disrupted daily life and businesses, with Seletar Airport seeing 16 diversions due to low visibility. Marina Bay Sands said certain outdoor experiences involving prolonged exposure to the outdoors have been temporarily suspended, while the hotel is providing masks and air purifiers to guests. Singapore's Minister for Digital Development and Information Josephine Teo said the government began preparations weeks earlier to support residents, including distributing masks to those most in need, and said Singapore has been in close contact with Indonesian officials and stands ready to provide assistance. Malaysia's Second Finance Minister Amir Hamzah Azizan said the worsening haze requires a coordinated Southeast Asian response and that Malaysia has offered to deploy water bombers and other resources.
