Multiple people are dead following a suicide bombing in Nigeria on Friday, reports indicate.
The bomber was suspected to be a part of the Boko Haram terrorist group, the Associated Press reported. The bomb was set off during a religious march featuring hundreds of Shiite Muslims.
Police have yet to give an official death toll. A local Shiite religious leader told the AP at least 21 members of his sect were killed in the blast. Another said at least 40 people suffered injuries.
The BBC reported the march continued after the attack, which occurred 13 miles south of Kano.
Boko Haram was recently named the world’s deadliest terrorist group by the Global Terrorism Index. There were 6,644 deaths attributed to the Nigeria-based group in 2014, the report found.
The Islamic extremist group has pledged allegiance to ISIS. Together, the two were behind more than half of the world’s terrorism-related deaths, according to the Global Terrorism Index.
Nigeria also experienced the largest increase in terrorism-related fatalities in 2014, according to the Global Terrorism Index. There were 7,512 terrorism deaths in the country, the report found.
