Suicide bomber kills at least 52 at park frequented by children in Lahore, Pakistan

The park is frequented both by residents and visitors to the city, and is popular with families.

“It was a soft target. Innocent women and children and visitors from other cities have been targeted,” Mr. Ashraf said. “Apparently, it seems like a suicide attack.”

There was no immediate claim of responsibility for the blast at the 67-acre park, which has walking paths as well as rides for children. The explosion coincided with violence in other parts of the country as hundreds of protesters took to the streets to condemn the Feb. 29 execution of Malik Mumtaz Hussain Qadri, who had killed Salmaan Taseer, a governor who had campaigned for changes in the country’s blasphemy laws, in January 2011.
