European Stocks Slide Amid Debt-Crisis Concern; Rio Tinto Drops

European stocks fell for a second day, extending losses from the Stoxx Europe 600 Index’s biggest quarterly drop since 2008, as concern deepened the region’s debt crisis will curb growth.

BHP Billiton Ltd. and Rio Tinto Group, the world’s biggest mining companies, declined more than 1.5 percent as copper tumbled to a 14-month low in London. Commerzbank AG and Societe Generale SA led losses in banking shares. Bayerische Motoren Werke AG sank to a one-year low.
