The number of those killed in multiple attacks in Pakistan on Friday has risen to 57, authorities said Saturday. Bomb and gun attacks caused chaos in three different cities, with both civilians and police among the victims. At least 39 people were killed and 216 injured in twin suicide bombings that rocked a crowded market area in the northwestern city of Parachinar. Both the so-called Islamic State and Jamaat-ul-Ahrar, an offshoot of the Pakistani Taliban, claimed responsibility for the blasts. Earlier Friday, at least 14 people were killed in an explosion targeting policemen in the southwestern city of Quetta. Four policemen were also shot dead in a drive-by attack in Karachi.
