Washington landslide: Moment's silence for victims

The number of people missing from last week's Washington state mudslide has been revised down substantially from 90 to 30, the authorities say.

The official death toll has risen to 18, with several bodies yet to be formally identified.

On Saturday rescue workers halted operations briefly to observe a moment of silence for those who died.
