Seattle's historic 'chewing gum wall' cleaned up

It is a popular tourist attraction in the United States, but not for much longer.

Seattle's famous "gum wall", said to be made up around one million pieces of chewing gum, is being cleaned up.

Officials at Pike Place Market say the wall attracts rats.

People first began sticking their gum to the wall while waiting for shows at a nearby theatre 20 years ago.
