Extremists kill 13 in Pakistan road attack

Suspected Sunni extremists opened fire on Shiite Muslims travelling through south-western Pakistan today, killing 13 people and injuring seven others in the latest apparent sectarian attack to hit the country, police said.

Sunni militants with ideological and operational links to al-Qaida and the Taliban have carried out scores of bombings and shootings against minority Shiites in recent years, but the past couple weeks have been particularly bloody.
