Thousands of Muslims gathered in London on Saturday at a rally "to fight extremism and promote a moderate, inclusive version of Islam." The event's organizers, Minhaj-ul-Quran International, said prior to the event that some 12,000 Muslims are expected at Wembley Arena. The group's founder, Muhammad Tahir-ul-Qadri, told journalists that killing innocents is forbidden in Islam and Muslims must integrate into the societies in which they are living.
