Citizens of Singapore marked the start of the new year by penning their wishes onto floating spheres.
Some 25,000 spheres filled Marina Bay next to the city-state's financial district to mark its 50th year of independence.
The Amazing Spider-Man stars Andrew Garfield and Emma Stone have joined in the Earth Hour festivities in Singapore:
A British wealth manager who lives in Singapore has apologised for referring to public transport commuters as "poor people", which sparked online outrage.
In another comment posted on Facebook, Anton Casey, a 39-year-old senior wealth manager in the financial sector, said he was washing "the stench of public transport off" him after travelling on the metro.
He also posted a picture of a boy, apparently his son, sitting inside a metro train with the caption saying: "Daddy, where is your car & who are all these poor people?"
Furious online readers flooded social media sites and criticised the Porsche-driving Mr Casey for his controversial comments.
Mr Casey, who is a permanent resident of the country and married to a former Singapore beauty queen, said: "I would like to extend a sincere apology to the people of Singapore. I have the highest respect and regard for Singapore and the good people of Singapore; this is my home.
"I wish for nothing more than to be forgiven for my poor judgement and given a second chance to rebuild the trust people have had in me as a resident of this wonderful country."
Firefighters are continuing to tackle forest fires in Indonesia that have led to a thick haze in some cities as well as Singapore and parts of Malaysia.
Hospitals in Dumai and Bengkalis in Indonesia's Riau province have recorded increases in cases of asthma, lung, eye and skin problems, health official Arifin Zainal told Reuters.
Free face masks are being distributed and authorities have advised residents to stay indoors with their windows shut.
Air pollution levels in Singapore have soared to a 16-year record high for a third consecutive day, as a smoky haze from forest fires in Indonesia shrouds the city state.
Its main air pollution index hit a measurement of 401 at midday, which is classified as "hazardous" and can aggravate respiratory ailments, the Associated Press reports.
Indonesia's Environment Minister met with Singapore's Environment and Water Resources Minister today to discuss solutions and efforts to mitigate the impact of the fires.
The haze is a recurring problem as a result of forest fires in the dry season, some of which are deliberately started to clear land for cultivation.
A haze is blanketing Singapore after fires in Indonesia, which could persist for weeks or even longer, according to the Prime Minister.
Lee Hsien Loong warned of consequences if Singapore-linked companies were found responsible for the burning.
The illegal burning of forests and other land on Indonesia's Sumatra island, to the west of Singapore, to clear space for palm oil plantations is a chronic problem, particularly during the June to September dry season.
At 1 pm local time yesterday, Singapore's pollution standards index (PSI) soared to a new high of 371, indicating air quality was "hazardous".
