Scores of prostitutes have taken to the streets of Amsterdam to protest moves to rejuvenate the city's famed Red Light District by shuttering windows where scantily-clad sex workers pose to attract clients.

The prostitutes say that the closures are depriving them of safe places to work.

Amsterdam municipality is involved in a long-term initiative to reinvigorate the historic network of canal-side streets and narrow alleys in part by reducing the number of brothel windows. Some 115 of the 500 windows have been closed in recent years.

About 200 people — prostitutes and their supporters — marched through the Red Light District Thursday evening carrying banners including one that read: "Don't save us, save our windows!"
