Members of the house of representatives have summoned security chiefs over the deadly clash between shi’ites and the police on Monday.
The lawmakers also went into a rowdy session over calls for the release of the group’s leader, Ibrahim El Zakzaky.
After a closed door session to deliberate further on the matter, lawmakers agreed to initiate a dialogue between the federal government and the group.
A deputy commissioner of police and a journalist were killed in Monday’s protest.
Police also said two other officers were injured, and fifty four suspects have been arrested. But the Islamic Movement of Nigeria claims eleven of its members were killed and at least thirty others were seriously injured.
The group is accusing police personnel of attacking what it calls, a peaceful protest to demand the release of its leader.
