LONDON -- Markets faltered Thursday after a surprisingly big rise in weekly U.S. jobless claims and ahead of a meeting of European leaders.

Sentiment in markets has been buoyant this week so a modest retreat was unsurprising. Propping up markets this week has been a run of positive U.S. economic news, expectations that Spain would soon request a bailout as well as some easing of concerns over the pace of the Chinese economic slowdown.
