Shares in Italian banks UniCredit SpA and Intesa Sanpaolo fell sharply on Friday and were briefly suspended for hitting the daily downward limit under pressure from Europe's debt crisis.

Brokers cited comments from European Central Bank board member Jose Manuel Gonzalez-Paramo on the euro zone debt crisis not being over, German comments on a possible sovereign debt roll-over, and Thursday's Moody's downgrade threat on Italian banks.
