London activists react to burkini ban in France

Activists created a makeshift beach Thursday outside the French Embassy in London as part of a demonstration against France's burkini ban.

So far 15 French towns have banned the burkini, a full-length swimsuit that covers the whole body except for the face, hands and feet. 

Officials say the ban on the outfit -- mostly worn by Muslim women -- is a response to growing terror concerns.

Wearing everything from bikinis to burkas, and even priest cloaks, demonstrators in London built sand castles and  brandished signs saying: "Wear what you want."
