The House of Representatives says it will investigate Monday's shooting at the Nasarawa State University where soldiers fired live ammunitions at protesting students, killing four.
Dozens of other students were reportedly injured.
The killings have sparked condemnations, but have surprisingly, yet to draw an official government response.
The students, in hundreds, demonstrated the lack of water and electricity on the school's Keffi campus, near Abuja. The scene soon turned violent after soldiers deployed to contain the restiveness clashed with the students shooting directly into their fold.
The Nigerian police confirmed the killings but denied that its officers were responsible for the shootings.
As of late Tuesday, police authorities in Nasarawa state, said they had limited details of what happened, but were continuing with investigations.
"The University shooting is still under investigation and once we are done with the investigation we will make the findings public," Michael Ada, the spokesperson for the police in Nasarawa, said.
The Nigerian Army, whose officers allegedly shot the students, is yet to comment on the killings.
The institution was subsequently closed by authorities.
In a resolution, the House mandated its committees on Army, Internal Security and Police Affairs to undertake a thorough investigation into the shooting and report to the House within two weeks.
The lawmakers observed a minute silence in honour of the slain students.
"The present case is one too many in cases of extra judicial killings by men of the Police and the Armed Forces that daily take place in University campuses and several parts of the country against defenceless, innocent Students and citizens and is thus very highly condemnable," the sponsor of the motion, Kingsley Chinda, (Rivers State), said.
