The Nigerian Labour Congress (NLC) has called for an urgent reorganisation of Nigeria's internal security system to check violent militant activities.
In a statement in Abuja on Monday, the NLC said that Saturday's attack on the Emir of Kano, Alhaji Ado Bayero, had once again questioned the efficiency of the security system in the country.
The statement signed by Mr Chris Uyot, the acting General Secretary of the congress, said that Kano State, being a major industrial city in the northern part of the country, was very strategic to the Nigerian economy.
It noted that Kano should not be allowed to be held hostage by violent groups.
"The Emir of Kano is one of the highest traditional office holders, and a leading traditional voice in the country.
"If he can be so brazenly attacked, ordinary citizens will continue to live in fear and consequently the atmosphere of insecurity in the state and the country in general will grow deeper.
"This will certainly affect the free movement of persons and workers to their workplaces with grave consequences on freedom of movement and commercial activities," it said.
While condemning the incessant attacks, the NLC also reiterated its call for dialogue, national peace and unity.
It called on those responsible for the violence to reflect on the devastating damages their attacks had on the economy and the future of Nigeria.
"We commiserate with the families of the aides of the Emir who lost their lives during the attack defending the life of the Emir of Kano.
"We also condole with workers and the people of Kano State and urge them not to despair or allow these attacks discourage them in the pursuit of peaceful coexistence and commerce.
"We urge the security agencies to improve their intelligence to protect lives and property and to ensure that subsequent attacks are detected and apprehended before they are carried out."
