European shares extended the previous session's losses on Tuesday, with miners losing ground and German energy firms RWE and E.ON falling sharply after a report saying they needed to set aside more money to shut down nuclear power plants.
The broader market also came under pressure, with nervousness ahead of the U.S. Federal Reserve's policy meeting on interest rates this week.
Shares in both RWE and E.ON fell more than 7 percent after Spiegel Online said the firms were as much as 30 billion euros ($34 billion) short of the money they need to set aside to build a safe disposal site for nuclear waste as part of Germany's exit from nuclear power.
E.ON, however, said that nuclear provisions were adequate.

At 0835 GMT, the pan-European FTSEurofirst 300 index was down 0.2 percent at 1,390.68 points. The index ended 0.5 percent lower in the previous session.
