On March 27, Christians all around the world celebrated Easter. Christians in Lahore, Pakistan were doing just that at a park filled with amusement rides for children, when, suddenly, the day took a tragic turn. A suicide bomber set off a bomb that ended injuring more than 341 people and killing at least 70.

Due to the location of the blast, close to the line for a train ride intended for children, most of the victims were women and children. A splinter group of the Pakistani Taliban — Tehreek-e-Taliban Pakistan Jamaatul Ahrar (TTP-JA) admitted to being behind the attack.

The Christian community in Pakistan, which consists of two percent of the population, faces constant adversity, segregation, and discrimination. TTP-JA spokesman Ehsanullah Ehsan told NBC News from an undisclosed location that “members of the Christian community who were celebrating Easter today were our prime target.”

The Pakistani army was issued to the park to try to control the crowds. In light of such a horrific event, volunteers and companies such as Uber and Facebook did their best to help in any way they could. Uber offered “free rides to blood donation centers.” Facebook started an “emergency check-in service” to let family members and friends to notify each other that they were safe. Volunteers helped bring the countless injured victims to hospitals and helped frantic victims reunite with their families.

Leaders around the world have condemned the attack, including the President of the United States, the Prime Minister of India, along with many others have called the attack “cowardly,” “shocking,” and “horrific.”
