Iran’s parliament has unanimously passed a bill designating the United States’ forces as “terrorists” over the assassination of top military commander Qassem Soleimani in an air attack in Iraq last week.

Soleimani, the popular head of the Islamic Revolutionary Guard Corps’ (IRGC) foreign operations arm Quds Force, was killed in a US drone attack outside Baghdad airport on Friday, ratcheting up tensions between the arch-foes.

Under the newly adopted bill, the entire US forces and employees of the Pentagon and affiliated organizations, agents and commanders and those who ordered the “martyrdom” of Soleimani were designated as “terrorists”.

“Any aid to these forces, including military, intelligence, financial, technical, service or logistical, will be considered as cooperation in a terrorist act”, - the bill said.
