Wall Street was mixed as better-than-anticipated US jobs data offset concern about political unrest in Egypt and ministerial resignations in Portugal.
In the US, private payrolls rose 188,000 in June, according to the ADP National Employment Report. That exceeded expectations for a gain of 160,000 jobs.
Separately, Jobless claims fell by 5,000 to 343,000 in the week ended June 29 from a revised 348,000 in the prior period that was higher than initially reported, according to the Labor Department.
"The [jobs] market is holding firm," Mark Zandi, chief economist at Moody's Analytics in West Chester, Pennsylvania, told Reuters.
All eyes now are on Friday's government employment report as investors are looking to better pinpoint the timing of a Federal Reserve downgrade of its bond-buying program. Nonfarm payrolls are forecast to have increased 165,000 in June, according to a Reuters poll of economists, while the unemployment rate will fall to 7.5 per cent.
