European stock markets rebound

London's benchmark FTSE 100 index rose 0.4 percent to 6,981.11 points.

In the eurozone, Frankfurt's DAX 30 index climbed 0.2 percent to 11,298.65 points and the Paris CAC 40 was up 0.6 percent to 4,995.77.

Global stocks tumbled Tuesday, with Frankfurt losing more than two percent, on geopolitical risks stretching from US tensions with Russia and Saudi Arabia to trade issues with China, as well as Italy's budget stand-off with the European Union.

Banking stocks were in focus Wednesday following mixed earnings from Deutsche Bank and Barclays.

Deutsche's share price slumped 3.4 percent, while Barclays rose 0.6 percent in initial deals.
