Duran Duran singer Simon Le Bon began suffering from throat problems in May, causing the cancellation of the band's UK tour dates. Now, the frontman's condition has worsened and the group has decided to cancel their upcoming European tour.

According to Duran Duran's website, the 52-year-old singer damaged muscles controlling his vocal cords, causing him to temporarily lose the top part of his vocal range. "I need to take some more time away from shows to get back to full strength," Le Bon said.

He added, "If we knew exactly when that might be, we wouldn't have to let this entire run of dates go, but what we feel we can't keep doing is moving shows piecemeal as it's just not fair on the fans."

While the group hopes to reschedule the dates, Le Bon is focusing on on his health and undergoing physical therapy to help his damaged muscles. "I am doing everything I can to work through this and get back on track as soon as possible."

The summer run, promoting the band's latest album 'All You Need is Now,'  was scheduled to begin on July 14 in Dublin and continue through mid-September. The band had also scheduled appearances at the iTunes Festival in London July 16, in addition to two dates at the V Festival in August.
