The group who christened themselves as 'Avengers', had declared a ceasefire last year after major attacks on oil facilities, crippling the OPEC member's oil output.
The attacks was said to have cut Nigeria's oil production, which stood at 2.1 million barrels per day (bpd) for some months in 2016.
Although the Nigerian government has been holding talks for more than six months with the region's leaders, the former militants have complained that no progress has been made.
NDA said, in a statement posted on its website Titled 'OPERATIONS WALLS OF JERICHO AND HURRICANE JOSHUA' it was set to resume fights against the Nigerian State.
“the people of our Niger Delta, sane minds in Nigeria and the comity of nations that the remaining 11 months and couples of weeks in 2017 will be filled with surprises and a reconfiguration of the struggle for the liberation of our motherland.”
“Since, the declaration of cessation of hostilities in the region by all fighters and affiliates, it has been evidently clear that the Nigerian state is not ready for any form of dialogue and negotiation with our people to addressing the issues sustaining the unending sufferings and deprivation of the people of the Niger Delta.
“The world is aware that, after listening to calls from our Royal Fathers, Community Leaders, Stakeholders and members of the comity of nations especially the governments of the United States of America, Great Britain and the European Union, we halted all actions.
This prospect for hope for a genuine dialogue and negotiations have been dashed and rejected.
“The world knows that PANDEF as team of critical stakeholders was mandated to engender a genuine dialogue and negotiations process that will be made of apolitical committed Niger Deltans to engage with the government and people of Nigeria, representatives of the International Oil Corporations and neutral observers. But this government decides to go around to politicising and blackmailing the process to forestall any genuine dialogue and negotiations.
“The world should be assured that, our next line of actions to redeem Operations Red Economy will be unannounced with surely overwhelming signatures to this government and humanity.
“The world is aware that the government of Nigeria has ear problems but we never knew that it has taken a detoriating deaf level dimensions. It is only through hard knocks we can speak to the Nigerian government henceforth”.
Continuing Avengers assured Niger Delta people that
“we feel your pains from these dashed hopes of a genuine talk once again. All fighters and commands are hereby placed on high readiness in your webs of operations to hit and knock the enemy very hard.
“That is the way to discuss with a deaf, when he cannot understand your soft massage. We are determined to hit him very hard and deadly that even his eyes will shed blood, his ear will be more deafened and his heart shall quake; when he sees, hear and feel the outcome of our next activities.
“On this note, we are declaring “Operations Walls of Jericho and Hurricane Joshua” simultaneously to reclaim our motherland and dislodge all cleavages the Nigerian Ruling oligarchy has foisted on the region that is sustaining the ongoing primitive accumulation by dispossession.”
