Pakistani police say they have arrested eight Shi'ite Muslims in connection with last week's riot in Karachi in which six employees of a U.S. fast-food outlet of KFC were killed.
The six men were killed after mobs of angry Shi'ite Muslims set fire to the restaurant and attacked other property following a bombing at a Shi'ite mosque that killed five people.
Police say the eight detainees are suspected of involvement in the riots, including the attack on KFC.
The Karachi mosque attack came three days after a suicide bombing at a Muslim festival in Islamabad that killed at least 19 people, mostly Shi'ites.
Investigators suspect that the outlawed Sunni militant group known as Lashkar-e-Jhangvi was behind both attacks. The group has ties with Afghanistan's former Taleban regime and with al Qaida.
