An alleged Pakistani militant has been sentenced to death by an anti-terrorism court in Karachi.
The court found Mohammad Faisal Pehlwan guilty of killing the leader of the Sunni Tehrik group and four others in May, 2001, the AFP news agency reports.
Police had to restore order after the May, 2001 killings
Police accused Pehlwan of being an activist of another Sunni militant group, Sipah-e-Sahaba.
The killings sparked rioting and demonstrations in Karachi.
The court ordered that Pehlwan be hanged. He was also fined 175,000 rupees ($3,017), AFP says.
In the May, 2001 attack, Maulana Saleem Qadri, chairman of Sunni Tehrik, was gunned down by unidentified assailants as they were on their way to pray at a mosque.
Pehlwan's lawyer said he was innocent. "I will challenge the verdict before a superior court," Ashraf Mughal declared.
Sipah-e-Sahaba (The Army of Prophet Mohammad's Companions) is a radical group from the majority Sunni sect of Islam.
President Pervez Musharraf has banned a number of groups in an attempt to stop killings between Pakistan's rival Islamic militant groups.
