Investigators have said that the four terrorists, who were responsible for gunning down 45 Ismailis in a bus attack near Safoora Goth last week, have revealed that they were also involved in the murder of human rights activist Sabeen Mahmud because of her campaign against Lal Masjid cleric Maulana Abdul Aziz.
Mahmud was shot dead shortly after hosting an event on Balochistan's "disappeared people", in the southern city of Karachi on April 25, reports the Dawn.
