Facebook CEO Mark Zuckerberg has a potential "life-saving tool" announcement to make.

Zuckerberg will unveil the tool today during "Good Morning America," while Chief Operating Officer Sheryl Sandberg will provide more details in an interview during "World News with Dianne Sawyer," ABC said on its site today.

There are few details on the announcement, although ABC has been plugging the segment all morning. Zuckerberg will be showing off the tool at the company's Menlo Park, Calif., headquarters.
