Stock indices closed mixed on concerns over new terrorist attacks. 129 people died in Paris on Friday.

The European Central Bank (ECB) executive board member Yves Mersch said on Wednesday that there is no indication that terror attacks in Paris will have a negative impact on the economy.

"We have no indication of any economic pessimism as a result of the Paris attacks, let alone weaker hard data. Doom-and-gloom talk is not warranted at this stage," he said.

Meanwhile, the economic data from the Eurozone was negative. The Eurostat released its construction production data for the Eurozone on Wednesday. Construction production in the Eurozone decreased 0.4% in September, after a 0.5% rise in August.

Civil engineering output gained 0.3% in September, while production in the building sector was down 0.6%.

On a yearly basis, construction output increased 1.8% in September, after a 1.8% decline in August. August's figure was revised up from a 6.0% drop.

Civil engineering output rose 2.4% year-on-year in September, while production in the building sector climbed 1.6% year-on-year.
