In addition to Ishaq's designation as a global terrorist, the State Department reviewed and maintained the Foreign Terrorist Organisation (FTO) designation of the LeJ.
The LeJ specialises in armed attacks and bombings and has claimed responsibility for numerous killings of Shia religious and civil society leaders in Pakistan.
It claimed a 2013 attack in a crowded billiards hall in Quetta that resulted in the death of 80 people, the State Department said.
As a result of maintaining the FTO designation, the legal consequences of the measure remain in place, including the prohibition against knowingly providing, or attempting or conspiring to provide, material support or resources to LeJ, and the freezing of all LeJ assets under the control or possession of US financial institutions.
