Salman Masood

Grief enveloped Pakistan after an instant of calculated cruelty thrust families onto a long roll call of bombing victims. “Within minutes, I lost my wife,” a man said. “I couldn’t save her.”

A powerful blast ripped through a public park in the eastern Pakistani city of Lahore Sunday evening, killing at least 52 people and wounding at least 200, including women and children, rescue workers and officials said.

The couple who carried out the deadly attack that killed 14 people here last week had long been radicalized and had been practicing at a target range days before their murder spree.
