Tehran - Iran summoned Nigeria's charge d'affaires to protest over the army's deadly crackdown on pro-Iranian Shiites in the north, the official IRNA news agency reported Tuesday.
The diplomat was told the foreign ministry on Monday that Iran "demands the Nigerian government immediately shed light on the incidents, treat the injured, and compensate for damages," IRNA said.
It said Foreign Minister Mohammad Javad Zarif also called for "immediate and serious action to prevent violence" against Shiites in a telephone call to his Nigerian counterpart Geoffrey Onyeama.
The army clashed on Saturday and early Sunday with the Islamic Movement of Nigeria (IMN) and arrested its leader Ibrahim Zakzaky.

The IMN seeks to establish an Islamic state through an Iranian-styled revolution.
"We have reports that bodies of our members killed outside the house of our leader are being evacuated in trucks by soldiers," IMN spokesman Ibrahim Musa told AFP.
Musa said victims of the violence included Zakzaky's wife, son and a former IMN spokesman.
The violence was sparked when Shiite faithful on Saturday blocked the main road outside their prayer centre, where hundreds had gathered for a ceremony.
The military claimed Shiites attacked a convoy of the army chief, Yusuf Buratai, leaving soldiers no option but to retaliate. The IMN, however, denied the charge.
