Karachi bus attack : suspected mastermind and several gunmen arrested
Chaudhry Nisar Ali Khan said the arrests were the result of an "excellent coordination between police and intelligence agencies" in Sindh province, of which Karachi is the capital.
The minister did not say when the arrests were made or give any details on the affiliation of the gunmen. He said some of those arrested confessed to taking part in the attack.
Both a Pakistani militant group linked to the Islamic State, which is fighting in Iraq and Syria, and a Pakistani Taliban splinter group have claimed responsibility for the May 13 assault during which gunmen stormed a bus with members of the Ismaili Shiite branch, forced them to bow their heads, then shot and killed them.
Sindh province's chief minister, Qaim Ali Shah, said during a televised news conference Wednesday that the arrested men were the same people who last month killed Sabeen Mahmud, a women's rights activist gunned down after she hosted a discussion forum about nationalists in the country's Baluchistan region, which has been engulfed in a low-level insurgency for years.
