U2 have rescheduled the US dates on their 360 degree world tour for next year, it's been announced.

The Irish band were forced to postpone the jaunt – originally scheduled for June – after singer Bono underwent emergency surgery on his back.

The dates will now begin at Invesco Field in Denver on May 21 and end in Minneapolis on June 23. All original tickets remain valid.

"We're delighted the dates are rescheduled and in all the same venues we originally planned to play," U2 manager Paul McGuinness said in the statement.

"Above all we want to thank the U2 fans for bearing with us. They're the best and the band wants to get back to where they belong, surrounded by their audience."

The injury also forced the band to miss their scheduled headline appearance at the Glastonbury festival last month.

The postponements are reported to have cost the band millions.
