Investing.com - European stocks succumbed to another slide in oil prices on Wednesday as markets waited cautiously for the outcome of the Federal Reserve meeting later in the day.
London's FTSE, Germany's DAX and France's CAC 40 all were lower, while the U.S. dollar was little changed against a basket of currencies.
Sentiment remained subdued after tech giant Apple (O:AAPL) forecast its first revenue drop in 13 years on Tuesday.
But the main pressure came from oil, which sank back towards $30 a barrel following its latest attempt at a bounce.
