Work to commence on 9/11 memorial

Construction finally begins on Monday at Ground Zero in New York of the memorial and museum remembering the 2,900 victims of the 9/11 attacks.

The design, Reflecting Absence, by architects Michael Arad and Peter Walker is controversial and attracting protests from some of the bereaved.

At 0800 (1300 GMT) 10 workers will quietly arrive to begin work on the memorial, due to open in 2009.

Next month work is due to begin on the Freedom Tower, the skyscraper intended to fill the void in Lower Manhattan's skyline (see below).
