A suicide bomber blew himself up in a mosque killing at least 10 Shiite minority Muslims, including six children, and wounded 12 others in a remote southwestern Pakistani town Thursday, officials said.

The attack took place as Shiites gathered at the mosque to observe the holy month of Moharram in the town of Chalgari in restive Baluchistan, some 170 kilometers (105 miles) southeast of the provincial capital, Quetta.

Sectarian violence – in particular that carried out by Sunni militants against Shiites, who make up roughly 20 percent of Pakistan's population of 200 million – has claimed thousands of lives in the country over the past decade.
