European shares extended losses in tandem with US stock index futures after worse-than-expected retail data from the United States showed consumers in the world's largest economy were turning more cautious.

The pan-European FTSEurofirst 300 index was down 0.7 percent to 983.11 points at 14:55 SA time. - Reuters
