The Nigeria Union of Journalists (NUJ) says the recent blockade of the nation's Senate House by state security agents calls for an overhaul of security agencies in the country.

"It is long overdue for our leadership to overhaul the security architecture of die country to make it work in tandem with the principles of democracy," the union said in a statement yesterday.

The "Siege on the National Assembly by some unscrupulous politicians using the Agents of the Department of State Security," the union says was primitive, reckless and a clear sabotage of the nation's democratic process.

"While we commend the swift reaction of the Acting President in sacking the Director General of the Department of State Security, Alh Lawai Daura, we however believe more needs to be done and quickly too, in fishing out all those involved in that dastardly act and punishing them accordingly," the statement by the NUJ National Secretary, Shuaibu Leman says.

The Union blamed the 'factor' heating up the political atmosphere in the country on excessive quest for power what by politicians, who it says ought to be working 'assiduously' to ameliorate the sufferings of the masses who voted them into office.

"This must abate immediately,"the statement says.
