Yussuff said the move was aimed at protecting lawmakers as the shi’ites, also known as members of the Islamic Movement in Nigeria (IMN), had stormed the assembly complex to protest the continued detention of their leader Ibrahim el-Zakzaky.
They were, however, stopped from entering the main complex.
“Report reaching me is that the Shi’ites have crashed the first gate, but I don’t know if we have enough security to handle the situation,” the deputy speaker said.
“In view of this, do we continue with the consideration of the reports before us or adjourn?”
Zakzaky has been in detention since December 2015 when his followers clashed with troops of the Nigerian Army in Zaria, Kaduna state.
He is facing trial over allegations of culpable homicide, unlawful assembly, and disruption of public peace.
