Citigroup Inc. said Thursday that hackers have accessed the credit card information of tens of thousands of its North American customers.

The bank said it recently discovered during routine monitoring that account information for about 1 percent of customers was viewed.

Citi has more than 21 million credit card customers in North America, according to its 2010 annual report. The New York-based bank didn't say exactly how many accounts were breached.

The hackers were able to gain access to Citi's Account Online service to view customer names, their account numbers and contact information including email addresses.
