Input: Islamabad, Pakistan (CNN) On Easter Sunday, a crisp spring day, some of the city's Christian population mingled with their Muslim neighbors, celebrating in a neighborhood park -- taking their kids on rides or pushing them on swings. Then, the sound of tragedy. Without warning, a blast tore through the park, killing indiscriminately. Because of the innocent setting, an unusually high number of those injured were women and children. But the attack, claimed by a splinter group of the Pakistani Taliban, intentionally targeted Christians, the perpetrators say. The suicide blast, in the eastern Pakistan city of Lahore, killed at least 69 people, a local government spokesman told CNN.Splinter group of Pakistani Taliban claims responsibility for the bombingSuicide bombing hits park Sunday evening when many families are out
