Libyan activists erect memorial wall

As Libyans in Tripoli celebrate the defeat of Muammar Gaddafi, a young activist group is putting up a memorial wall to display the names and faces of fellow Libyans who have died.

While no one knows how many people were killed in the months-long battle for a free Libya, it is believed to be thousands. These activists want them all to be remembered.
