Four Americans are among the dead, a U.S. State Department official told NBC News.  Two were identified last week as Justin and Stephanie Shults, an American couple who worked as accountants in Brussels. The other two have yet to be named. Three attackers were also killed last Tuesday; authorities are seeking a fourth man in connection with the attacks. Four people have been arrested and charged so far.

Who was behind the deadly attack in Lahore? A Taliban splinter group claimed responsibility for the bombing that killed more than 70 people and wounded 300 others. Pakistani security agencies said a number of “suspected terrorists and facilitators” were arrested following the attack on a park where Christians were celebrating Easter. Still, most of the victims were Muslim.
