The suspect believed to have shot Pakistan’s Interior Minister Ahsan Iqbal on Sunday was affiliated to the new ultra-religious Tehreek-e-Labaik party, according to a police report seen by Reuters.

Reuters report said the shooter was Abid Hussain, 21, who “showed his affiliation” to the party, which focuses on highlighting and fighting blasphemy. It did not speculate on his motive.

Labaik’s leader, Khadim Hussain Rizvi, condemned the attack in a statement and said his party had not authorized any of its workers to take up arms.

Iqbal, 59, a senior member of the ruling Pakistan Muslim League-Nawaz (PML-N) party and a staunch ally of ousted premier Nawaz Sharif, was shot as he was leaving a constituency meeting surrounded by supporters in Punjab province.

An initial report on the shooting by a local administrator, the deputy commissioner of Narowal district, seen by Reuters, said the gunman had been arrested and “showed his affiliation” to Tehreek-e-Labaik.

The party calls for the aggressive enforcement of Pakistan’s blasphemy laws, which can carry the death penalty.

However, neither the report nor other officials commented on the attacker’s possible motives, the Reuters report said. 

Iqbal was shot soon after addressing voters in Kanjroor village in Narowal, his constituency near the border with India, but the exact circumstances were not immediately clear.
