A Pakistani security official collects evidence a day after a bomb attack hit the 13th century Muslim Sufi shrine of Lal Shahbaz Qalandar.

At least 75 people were confirmed dead and 100 others injured when a suicide bomber targeted the shrine of Lal Shahbaz Qalandar in Sehwan, a city located in the Jamshoro District in the Sindh province of Pakistan.

The attack is being considered the deadliest to hit Pakistan in nearly two years.

The Islamic State of Iraq and Syria (ISIS) group claimed responsibility for the blast via its Amaq propaganda website.

“The loud explosion took place inside the complex of the shrine near the gate,” the Assistant Superintendent of Police in Sehwan told Geo News.

The shrine is known to be frequented by large numbers of people on Thursdays.
