Sidelined by a knee injury, the Cranberries lead singer Dolores O'Riordan headed home to Ireland for surgery, forcing cancellation of remaining gigs on the band's Australian tour.

In a statement issued Saturday, O'Riordan said the band regretted having to leave."Playing live is important to us and so far this tour has been an incredible experience," she said. "We feel terribly for people who were planning to attend the concerts and have supported us since the beginning."
