America plays emotional tribute on Sept 11 anniversary

With quavering voices, parents and grandparents of those killed at the World Trade Center in New York slowly read the names of the victims today to mark the third anniversary of the attacks that brought down the twin towers.

Moments of silence were observed at 8:46 and 9:03 am (1246 and 1303 GMT), the times two planes slammed into the towers on September 11, 2001, and at 9:59 and 10:29 (1359 and 1429 GMT), when the two towers collapsed.
