Stock indices closed higher after the mixed economic data from the Eurozone. The ZEW Center for European Economic Research released its economic sentiment index for Germany and the Eurozone on Tuesday. Germany's ZEW economic sentiment index declined to 12.1 in September from 25.0 in August, missing expectations for a fall to 18.4.

"The weakening economic development in emerging markets dampens the economic outlook for Germany's export-oriented economy. While economic growth in the second quarter was largely driven by external demand, it is becoming less likely that exports will stimulate growth in the near future," the ZEW President Clemens Fuest.

Eurozone's ZEW economic sentiment index decreased to 33.3 in September from 47.6 in August.

Eurozone's unadjusted trade surplus jumped to €31.4 billion in July from €26.4 billion in June.

Exports rose at an annual rate of 7.0% in July, while imports increased at 1.0%.

Eurozone's employment increased by 0.3% in the second quarter, after a 0.2% rise in the first quarter. The first quarter's figure was revised up from a 0.1% gain.

The Office for National Statistics (ONS) released the consumer price inflation data for the U.K. on Tuesday. The U.K. consumer price index declined to 0.0% in August from 0.1% in July, in line with expectations.

The decline was driven by low petrol prices.

On a monthly basis, U.K. consumer prices rose 0.2% in August, in line with expectations, after a 0.2% decline in July.

Consumer price inflation excluding food, energy, alcohol and tobacco prices fell to 1.0% in August from 1.0% the month before.

The Retail Prices Index remained climbed to 1.1% in August from 1.0% in July, beating expectations for a decrease to 0.9%.

The consumer price inflation is below the Bank of England's 2% target.

The U.K. house price index rose at a seasonally adjusted rate of 0.8% in July, faster than a 0.6% in June.

The increase was mainly driven by a rise in prices in the east and south-east of England.

On a yearly basis, the U.K. house price index increased at a seasonally adjusted rate of 5.2% in July, down from a 5.7% gain in June. It was the lowest rise since September 2013.

The lower house price inflation was mainly driven by a decline in prices in Scotland and the north-east of England.
