ANCHORAGE, Alaska (AP) — The Catholic Diocese of Fairbanks plans to file for bankruptcy after negotiations to settle sexual abuse claims failed, the bishop said Wednesday.

Bishop Donald J. Kettler said he anticipates filing for Chapter 11 bankruptcy protection within five weeks.

"I am legally and morally bound to both fulfill our mission and to pursue healing for those injured," he said in a prepared statement.

More than 150 claims were filed against the Roman Catholic church, alleging abuse by clergy or church workers between the 1950s and 1980s. The plaintiffs' lawyer Ken Roosa said 135 of those cases are still pending.
