Stock indices closed lower as investors remained cautious due to new debt deal talks between the European Union and Greece. It's unlikely that the agreement will be reached today.

Eurozone's trade surplus increased to €24.3 billion in December from €21.2 billion in November, exceeding expectations for a rise to €21.3 billion. November's figure was revised up from a surplus of €20.0 billion.

The increase was driven by lower imports.

Exports climbed by 1.0% in December, while imports fell 2.0%.

Exports were boosted by a weaker euro and lower oil prices.
