“The persistence of terrorist attacks in different parts across the world reflects the need for the adoption of policies and necessary measures for an effective and all-out campaign against terrorism and extremism,” Foreign Ministry Spokesman Hossein Jaberi Ansari said on Thursday.
At least at least 22 worshippers were killed on Wednesday, when two female bombers attacked a mosque in the northern Nigerian city of Maiduguri, the birthplace of the Boko Haram terrorist group.
The first bomber struck inside the mosque on the outskirts of the city, while the second blew herself up outside the building as survivors tried to flee.
Abdul Mohammed, of the State Emergency Management Agency, said at least 17 other people were also wounded in the explosions.
According to the coordinator of the local civilian self-defense Vigilante Group, Abba Aji, the mosque in Umarari served as a military command center in the Nigerian army’s war against the Boko Haram terrorist group.
No group has so far claimed responsibility for the explosions but such attacks are usually blamed on Boko Haram militants.
Boko Haram has recently been using bomb attacks as Nigeria’s military pushes the Takfiri group out of territories they once controlled.
In recent months, several Boko Haram assailants have blown themselves up at roadblocks into the city that are manned by army troops and local vigilantes.
Some 20,000 people have been killed and about 2.3 million displaced since the group started its violent campaign in Nigeria in 2009.
