A devastating explosion, claimed by the Islamic State, ripped through a Sufi shrine in Sehwan town of Pakistan's Sindh province on Thursday, killing at least 72 people, including 12 women and four children, and injuring over 250 others.
Pakistan has waged several offensives against militants in recent years, including a major operation that started in mid-2014 in the last key insurgent sanctuary of North Waziristan.
Initial report suggests that it was a suicide bombing on portion reserved for women in the shrine, the Dawn reported, quoting SSP Jamshoro Tariq Wilayat. The shrine was crowded today because Sufis consider this a sacred day of prayer.
The local administration has sought night-vision helicopters from the army to shift the seriously wounded people to Hyderabad or Karachi. Another six people were killed Wednesday in a bombing in Peshawar. Senior police officer Shabbir Sethar feared the death toll might go up.
