At least 47 people were killed and over 110 others injured in the bomb blast that hit Shah Noorani shrine in Lasbela district, some 100 kilometers north of the port city of Karachi, on Saturday evening.
Iran’s Foreign Ministry Spokesman Bahram Qassemi said on Saturday that collective efforts and resolve are essential to uproot terrorism in the region.
He extended his condolences to the Pakistani government and nation as well as the families of the victims of the terrorist crime.
Pakistani Prime Minister Nawaz Sharif denounced the bomb attack and called on authorities to speed up the rescue operation.
Reports say some 500 people were in the shrine when the bomb went off.
The Daesh terrorist group has claimed responsibility for the deadly attack.
Pakistan’s restive and mineral-rich Balochistan province is rife with separatist, extremist and sectarian violence and has been the scene of several bomb and gun attacks over the past years.
