An explosion-like fire incident on Sunday night hit Rivers House of Assembly.
The fire reportedly started around 10pm, and it took firefighters several hours to extinguish the blaze.
It was learnt that more than 10 fire trucks were drafted to combat the fire incident.
The cause of the fire is still under investigation.
Videos circulating online show the charred remains of the assembly chamber, with the roof and walls completely destroyed.
The fire comes amid rumours of alleged rift between Governor Siminalayi Fubara and his predecessor, Nyesome Wike, now Minister for the Federal Capital Territory (FCT).
The development also came amid an alleged impeachment plot against Governor Fubara by the Rivers Assembly.
