At least seven people have been killed in a twin bombing in the Pakistani city of Karachi. Local officials say 40 people --including women and children -- were also injured in the blasts. Reports say the bombs went off in a Shia area of the city. It\'s not clear who carried out the attacks. But al-Qaeda and its offshoots were behind similar incidents in the past. Meanwhile, a group of protesters have staged a demonstration in the city of Lahore to condemn a recent attack on a Shia religious procession in Rawalpindi. Protesters censured the local government for failing to provide proper security for Shia mourners and demanded that the perpetrators of the attack be brought to justice. Show Less >>
