ISLAMABAD -- Authorities in Pakistan say they have arrested a key orchestrator of the suicide attack that killed three Chinese teachers at Karachi University in April, while Beijing signaled on Wednesday that it appreciates the "positive efforts" but still expects more to be done to protect its people and interests.
The government of Pakistan's Sindh Province on Tuesday said it had caught the alleged mastermind behind the attack, which was carried out by a female bomber. Three Chinese instructors at the university's Confucius Institute were killed, along with a Pakistani driver. The accused planner and facilitator, Dad Bakash, was brought before an anti-terror court in Karachi.
