Europe fears keep markets on edge

Concerns that Europe's debt crisis could drag down parts of the continent's banking system hit most global markets today, though social network Facebook's imminent flotation buoyed sentiment on Wall Street.
Spain's main stock index recovered 1.34% from heavy losses yesterday, thanks mainly to a bounce back in the shares of state-controlled lender Bankia, which had plummeted on reports of an increase in deposit withdrawals. They rose 22% today, making up for a similar drop the previous day.
