U.S. credit card provider Visa said Thursday that a payment processor in Iceland briefly opened the floodgates to donations to secrets outlet WikiLeaks, so they took the necessary steps to close them again.

Icelandic payments processor DataCell had said the blockade was lifted yesterday after months of stalling from Visa and MasterCard, who cut off all funding for WikiLeaks in Dec. of last year.

The firm had contracted with another payments processor to enable WikiLeaks donations for a few brief hours, before Visa noticed and ordered it shut down.

DataCell previously threatened legal action against Visa and MasterCard over their blockade of WikiLeaks' payments, which they said had hurt their business. They did not file the necessary paperwork, however.
