ISLAMABAD: Supporters of a political party in Pakistan used the anniversary Sunday of the Sept. 11 attacks to stage anti-American protests.

In Islamabad, about 100 people chanted and held up banners that repeated conspiracy theories alleging American or Israeli involvement in the attacks.

Such theories have been commonly aired among Islamist and militant sympathizers since the attacks in 2001.

A smaller demonstration also took place in the central Punjabi city of Multan.

In the sprawling city of Karachi, around 100 people protested against the war in Afghanistan that was launched in the wake of the Sept. 11 attacks.

The demonstrations were organised by Jamat-e-Islami, the country's largest Islamist political party, which frequently rallies its base by protesting against America and what it say is a US war on Islam.

Pakistan has been hit by hundreds of bombings since Sept. 11, 2001, by al Qaeda and Taliban militants.
