A protest by members of the Islamic Movement in Nigeria (IMN) turned violent on Monday in Abuja.
The protesters reportedly clashed with security agencies close to the Federal Secretariat in the Nigerian capital.
Monday’s incident comes about two weeks after two Shiites were killed and two police officers injured after a similar protest turned violent at the National Assembly complex in Abuja.
The Shiites are demanding the release of their leader, Ibraheem El-Zakzaky, who has been in detention for alleged murder since December 2015.
On Monday, the Shiites had begun a protest at Nitel junction and were expected to end at the secretariat.
Government vehicles including those owned by the emergency management agency were burnt by the aggrieved protesters.
Some other sources alleged that the Shiites threw petrol bombs as part of the protest.
In an interview, a member of the Shiite group, Yahaya Mohammed, said the Shiite members were only having a peaceful protest when military officers attacked them.
Following the violent protest at the National Assembly, the police last week directed that protests in Abuja be limited the Unity Fountain, near Transcorp Hilton hotel, Abuja.
