The lead from Wall Street was glum as investors there braced themselves for another disappointing non-farm payrolls report Friday after an up-and-down week of economic data.
It began with figures showing the economy grew at a slower pace than forecast in the January-March first quarter while two days later a study revealed a surprise rise in manufacturing activity.
US payrolls firm ADP said just 119,000 private sector jobs were created in April, well off the forecast 170,000, signalling the recent surge in employment could be tailing off.
And while data showed Thursday that jobless claims dipped in the previous week, that was overshadowed by news the all-important services sector had grown slower in April than March.
"As concern over US growth robustness is intensifying, the jobs number will provide further clues for assessing the US outlook and the (Federal Reserve's) stance," said Kintai Cheung, strategist at Credit Agricole, in a note.
Economists expect Friday's jobs report to show the economy created just 162,000 jobs last month, while unemployment stayed at 8.2 percent.

The European Central Bank on Thursday held interest rates at historic lows but held off making any more decisions on boosting the region's struggling economy, despite figures showing unemployment at a record high of 10.9 percent.
France goes to the polls Sunday to choose between Sarkozy and his Socialist opponent, who has said he would put the country on a more growth-oriented course, instead of austerity.
Hollande's position has raised concerns among France's neighbours that it could hurt the eurozone's second-biggest economy, leading to a fresh crisis.
