Shops have been closed in Pakistan's eastern city of Lahore to protest recent suicide bombings. At least 42 people were killed and 175 wounded when two suicide bombers struck Pakistan's most important Sufi shrine on Thursday.

All major markets and business centers were closed for the strike called by a religious alliance. Major markets in the southern city of Karachi were also closed in response to the strike call.

Meanwhile, Prime Minister Yousaf Raza Gilani visited those injured in the blasts at Lahore hospital on Saturday. No group claimed responsibility for the shrine attack, but authorities suspect al-Qaeda linked militants.
