Chicago -

Internal documents showing how officials from the Archdiocese of Chicago handled allegations of child sexual abuse by priests are about to become public.

Victims' attorneys will post thousands of documents online on Tuesday, about a week after receiving them from the archdiocese as part of legal settlements.

Attorneys say the documents will show the archdiocese concealed the abuse for decades, including moving priests to new parishes where they molested children again.

Cardinal Francis George says the disclosures are an attempt at transparency and a means to help victims heal. He's also apologised to victims and area Catholics for the abuse.

He's stressed the documents pertain to abuse that happened before he became archbishop.

The documents are for 30 of 65 priests for whom the archdiocese says it has credible allegations. - Sapa-AP
