Nigerian Police Minister, Muhammad Maigari Dingyadi, has told the BBC that soldiers were not instructed to shoot at protesters.
"Soldiers have already spoken about this, they are denying their involvement and government is aware that they have not given any soldiers instructions to go into this crisis, not at all," Mr Dingyadi told the Newsday programme in an interview.
His remarks come after Amnesty International said at least 12 people were killed by soldiers and police in Lagos on Tuesday.
Nigeria's army has dismissed the reports as "fake news".
The minister said the ongoing anti-police brutality protests in the country had been hijacked by rogue elements. He said the government was working on all the demands for reforms demanded by protesters.
He said President Muhammadu Buhari's administration inherited a bad system which it is currently reforming.
