Plenary at the Senate on Thursday became disorderly over alleged incompetence of President Muhammadu Buhari to address the sequence of killings by armed herdsmen.

‎A lawmaker representing Abia South Senatorial District, Senator Enyinnaya Abaribe, had raised a point of order to make reference to the conflicting reasons given by officials in the Buhari-led administration for the herdsmen/farmers clashes.

Abaribe noted that the latest was from Buhari who said during his current official visit to the United Kingdom ‎that the killer herdsmen were from Libya.

He said the admittance by the President that Nigeria had been invaded by external forces confirmed his previous claims that Buhari ‎was “totally incompetent”.

The Majority Leader, Senator Ahmad Lawan, interrupted Abaribe to raise a point of order, asking the lawmaker to withdraw his derogatory comments on Buhari and apologise for his statements.

The bickering polarised the chamber along political lines.
