Wikileaks condemns companies for cutting ties with website
Mastercard has become the latest company to be targeted by hackers who have pledged to pursue firms that have withdrawn services from Wikileaks.
Online retailer Amazon and internet payments processor Paypal have also cut links with Wikileaks.
Wikileaks spokesman, Kristin Hrafnsson, said he condemned all companies who had cut ties with the website claiming they were bowing to pressure from the US government.
