Islamic State claimed responsibility via their Amaq News Agency for the suicide bombing at Pakistan’s Lal Shahbaz Qalandar Sufi shrine that killed at least 70 people and wounded 250. According to al Jazeera, the terrorist attack occurred while hundreds of people were gathered for a ritual.

The explosion went off at the Lal Shahbaz Qalandar Sufi shrine in the town of Sehwan, in Sindh province, as a ritual was being performed.

Sikandar Mandhro, Sindh’s health minister, told Al Jazeera: “There was a huge crowd gathered there for the [religious gathering] at the shrine, and there was a very big explosion.”

Hundreds of people, often thousands, gather at the shrine every Thursday to pray and participate in the Sufi tradition of dhamaal – a form of devotional percussion and dance.” – Al Jazeera
