Rock star Bono has cancelled his visit to Doha next week.
The frontman of U2 and global activist has suddenly pulled out from attending the UN Conference on financing for Development held here this week.
He was also slated to be a guest on a special edition of the Doha Debates, part of the Qatar Foundation and broadcast on BBW World satellite channel.
A spokeswoman for the Doha Debates said Bono's representatives had said his withdrawal was due to "unforeseen circumstances" and was unable to elaborate.
On Wednesday Bono's charity ONE issued a statement confirming his arrival in Doha this weekend.
