(Al Jazeera) – At least 70 people – mostly women and children – have been killed at a crowded park in Pakistan in a suicide blast that also wounded more than 300 people, officials said. A faction of the Pakistani Taliban, Jamaat-ul-Ahrar, later claimed responsibility for the attack in the eastern city of Lahore and said that it was aimed at Christians. Al Jazeera’s Kamal Hyder, reporting from the capital, Islamabad, said Christians were celebrating Easter Sunday at Gulshan-e-Iqbal Park, which is popular with families, when the bomber blew himself up a few metres from a children’s play area.
