Memorial tribute: Horrors of 9/11 still linger

In the park where the Twin Towers once stood, a new memorial highlights the lingering impact of the September 11 attacks.

A memorial has been unveiled in New York to remember increasing numbers of 9/11 victims.

Hundreds of thousands of people were exposed to toxic dust from the collapse of the World Trade Center buildings in 2001.

And first responders continue to suffer from ill health.
