Here's the link to the US State Department's designation of Qari Zakir as a Specially Designated Global Terrorist under Executive Order (E.O.) 13224. The Haqqani Network itself was designated in September.
As chief of suicide operations for the Haqqani Network, Zakir has been responsible for some terrible atrocities, listed in the designation, which allows the US to freeze any assets of his it finds under its control.
Both Zakir and the Haqqani Network itself were also designated by the UN 1988 Sanctions Committee yesterday, which requires all UN member states to implement an assets freeze, a travel
ban, and an arms embargo against them.
