There appeared to be limited market reaction to news that French authorities had killed two suspects after last week's attacks in Paris, which killed more than 120 people. Some European travel and leisure stocks lost ground but they were in line with the overall European market.
The pan-European FTSEurofirst 300 index, which rose 2.6 percent in the previous session, fell 0.6 percent while the euro zone's blue-chip Euro STOXX 50 index declined by 0.8 percent.
Air Liquide dropped 4.9 percent after the company announced a $13.4 billion deal to buy U.S. peer Airgas.
