Akon's international booking agents, American Talent Agency, said in a statement they had postponed the show following violent protests against the artist, but were working to secure a new date.

On Monday, hundreds of rock-throwing protesters attacked the headquarters of Sri Lanka's largest private broadcaster, which was the media sponsor of Akon's planned April concert. Four people were injured.

The protesters were apparently angered by the "Sexy Bitch" video by French DJ David Guetta featuring Akon, in which a statue of the Buddha on top of a building appears briefly in the background as dozens of scantily dressed women dance near a pool.

"I was not aware that the statue was even on the set of the video until now. I would never set out to offend or desecrate anyone's religion or religious beliefs," Akon said in a statement.

The government has said it would deny Akon a visa to enter the country as a result of the religious uproar.

"I myself am a spiritual man, so I can understand why they are offended, but violence is never the answer and I am disheartened," Akon said.

Sri Lanka's Buddhist clergy are hugely influential in ordinary life and politics, and in the past hardline Sinhalese nationalists have become violent against those they see as offending Buddhism.

In December 2004, a hand grenade attack at a concert by Bollywood star Shah Rukh Khan that killed two people and wounded 19 was blamed on Sinhalese nationalists angry the concert fell on the first anniversary of the death of a renowned Buddhist monk.
