Stating that the Pak-US ties need to be reviewed, the extremist leader said the US had started targeting the Islamic nation, but the members of the Defa-e-Pakistan, would defend the countr's "ideological frontiers".
If these people "adopt an aggressive stance and try to attack Pakistan, the US will break up."
Former Inter-Services Intellgence chief, Hamid Gul, son of former General Zia Ul Haq and Pakistani politician Sheikh Rashid Ahmed, also attended the rally.
Jamiat Ulema-e-Islam (Sami) chief Sami-ul-Haq too addressed the gathering and said that if "US, Israel, India or NATO forces" attacked Pakistan, the Defa-e-Pakistan Council will retaliate with "full force".
Haq said the Council wants to free Pakistan "from the clutches of the US and its allies" and end US drone attacks in the country.
