The blast occurred when many of the victims had lined up to buy tickets for a train ride, which included 36 children. Lahore Police Chief Haider Ashraf said, "Mostly women and children are killed and injured in the blast". He further added that the park was busier than usual as Easter Sunday was being celebrated and that’s why the soft target was chosen and he (suicide bomber) went towards women and children in the park. More than 72 people were killed and at least 320 others injured when the suicide bomber targeting mainly Christians blew himself. Twenty-four children were among the dead, according to Punjab province police.
The State Department called the attack a "cowardly act". Officials said that they had recovered the suicide bombers body and he appeared to be aged in his mid-to-late 20s. The police further said that he had carried more than 30 pounds of explosives.
The responsibility of the attack is claimed be by a splinter group of the Pakistani Taliban — Tehreek-e-Taliban Pakistan Jamaatul Ahrar (TTP-JA). From an undisclosed location and while using an Afghan cell number, TTP-JA spokesman Ehsanullah Ehsan informed that the Members of the Christian community who were celebrating Easter were their prime target. The group vowed more such attacks.
Pakistani Prime Minister Nawaz Sharif canceled a planned visit to the United States after the violence, telling his nation Monday in a televised address that his government would not allow terrorists to "play with Pakistani lives".
"We are keeping count of every drop of the blood of our martyrs," he said. "We will not rest until the cost of this blood is avenged”.
Army chief Gen. Raheel Sharif promised Pakistan "will never allow these savage non-humans to over run our life and liberty". Three days of mourning in the province is announced by Punjab Chief Minister Shabaz Sharif.
Over 2 million Christian populations stay in Pakistan, which is a majority-Muslim state.
