Bono has said he is "so happy and relieved" to be able to continue U2's European tour after a dramatic night onstage in Berlin on Saturday which saw him losing his voice and the band scrapping the show after a couple of songs.

In a message posted on U2's website, Bono said: "I've seen a great doctor and with his care I'll be back to full voice for the rest of the tour. So happy and relieved that anything serious has been ruled out. 

"My relief is tempered by the knowledge that the Berlin audience were so inconvenienced. There was an amazing atmosphere in the house, it was going to be one of those unforgettable nights but not for this reason… We can't wait to get back there on November 13."

News agency AFP had reported that Bono appeared to be struggling with his vocals a few songs into U2's set at Berlin's Mercedes-Benz Arena - their second date in the German capital after the Friday night opener of the iNNOCENCE +eXPERIENCE European Tour.

Bono drank from a flask a number of times before deciding he could no longer continue the show. It was thought that smoke machines may have affected his voice.

"I think we can't go on. It's not right for you," an upset Bono told the crowd.

The band left the stage as the crowd waited to see if the show would resume, but fans were soon told the concert was over. 

A statement on the band's website on Saturday night read: "We're so sorry for tonight's cancellation.

"Bono was in great form and great voice prior to the show and we were all looking forward to the second night in Berlin, but after a few songs, he suffered a complete loss of voice.

"We don't know what has happened and we're taking medical advice."

"As always, we appreciate our audience's understanding and all our fans' support in Berlin and those who travelled from afar. We will update you very soon," the statement added.

The band's next concert is scheduled for Cologne on Tuesday September 4.

U2 are set to play Belfast's SSE Arena on October 27 and 28 and Dublin's 3Arena on November 5, 6, 9 and 10.

The Dublin date on November 10 had been pencilled in as the final date of the tour, but the rescheduled show in Berlin on November 13 will now see the European trek end where it began.
