Pop star Bieber brings cheer in typhoon-hit Philippines

Bieber flew unannounced to the central city of Tacloban just over a month after it was devastated by Super Typhoon Haiyan and sang Christmas carols to children at a heavily damaged local school amid tight security, witnesses said.

"He sang 'Holy Night' for the children," said Kate Donovan, a spokeswoman for the United Nations Children's Fund (UNICEF), one of three aid agencies expected to benefit from Bieber's charity work.

An AFP reporter said Bieber also played basketball at an improvised sandlot court with some of the young boys, later hugging some of them and posing for photos.

"UNICEF is very pleased that Justin Bieber wanted to visit Tacloban, and stopped by City Central Elementary School which has suffered a great deal of structural damage," UNICEF emergency coordinator Angela Kearney said.

"Justin brought a lot of joy, hope and cheer to the hundreds of children who were there," she added.

The money that would be raised would give child survivors access to education, vaccinations, clean water and sanitation, she said.

Prior to visiting the Philippines, Bieber, 19, had posted a message on fund raising website Prizeo.com urging his millions of fans to donate to the victims of the typhoon, the strongest to ever hit land.

Haiyan cut across the central Philippines on November 8, destroying scores of communities along its path.

Tsunami-like storm surges it triggered also swallowed up many coastal areas, and were blamed for majority of the nearly 6,000 deaths.

More than 1,700 others remain missing and about four million have been displaced.

In his message on Prizeo, Bieber, one of the most followed persons on Twitter and best known for hit songs such as "Baby," "Boyfriend" and "Beauty and a Beat", said those donating to his cause could win a chance to personally see him record music next year.

"In the wake of Typhoon Haiyan, its victims in the Philippines need our help -- and they need it now," the Canadian singer said in his appeal.
