US house prices continued to fall in January, but at a slower pace than in the previous month, a closely-watched survey has suggested.

The Case Shiller housing index, which is compiled by rating agency Standard & Poor's, was down 3.8% from a year ago.

Sixteen of the 19 cities covered by the survey showed price falls.

Separately, figures suggested consumer confidence in the US dipped in March after rising sharply in the previous month.
