QUETTA, Pakistan: At least 22 people were killed in three attacks in Pakistan on Tuesday, officials said, including 11 who died after a suicide bomber targeted a political rally in the southwestern province of Balochistan.

Another 40 people were wounded in that explosion, which took place in the parking lot of a stadium in the provincial capital, Quetta, where hundreds of members of the Balochistan National Party (BNP) had gathered, two provincial officials said, speaking on condition of anonymity.

Another attack in Balochistan, near the border with Iran, claimed five lives on Tuesday, while six soldiers were killed after a suicide attack on their base in Khyber Pakhtunkhwa province.

Balochistan is Pakistan’s largest and most resource-rich province, but also its poorest, and regularly ranks among the lowest on human development indicator scorecards.

The BNP campaigns on a platform calling for greater rights and economic investment in the wellbeing of members of the Baloch ethnicity.
