Nasiruddin Haqqani, the brother of the powerful Pakistani Islamic militant group's leader who also functioned as a senior commander and fundraiser for the Haqqani network, was fatally shot Monday in Islamabad, sources in the Taliban and in Pakistani intelligence told CBS News.
The Haqqani network has been one of the most lethal forces battling U.S. troops and their allies in neighboring Afghanistan, and Nasiruddin's death represents a significant blow to the organization.
