国际英语新闻：73 killed in fresh suicide bomb attack in Pakistan

A banned Sunni radical group called Lashkar-e-Jhangvi later claimed responsibility for the attack. The Punjab-based terrorist group founded in 1996 was also claimed carrying out at least two suicide bomb attacks on a Shiite Muslim mourning procession in Lahore, capital of the eastern Pakistani province of Punjab, on Wednesday night, killing 37 people and injuring over 200 others.

On Thursday night, a spokesman of Lashkar-e-Jhangvi said that the attacks were in revenge for the killing of their leaders by Shiite Muslims and threatened more attacks against Shiites.

Friday's suicide blast in Quetta was the most serious one of its kind since the end-July in Pakistan which was also devastated by the worst flood in living memory.
