The Nigerian Army has spoken on its invasion of the offices of Daily Trust newspaper on Sunday.
Soldiers stormed the offices of Daily Trust in Borno and Abuja on Sunday and arrested some members of staff. They also took away some equipment from the offices.
The officers eventually left the premises on Sunday night after a directive from the presidency.
Sani Kukasheka Usman, Director of Army Public Relations, issued a statement on Monday to clarify what necessitated the invasion.
According to the Army, the newspaper disclosed classified military information, which undermined national security.
The statement read: "The Nigerian Army wishes to clarify on alleged invasion of Media Trust Headquarters in Abuja and regional office in Maiduguri. We would like to state that soldiers of the Nigerian Army along with elements of Nigeria Police Force and other Security Agencies were indeed at Abuja and Maiduguri offices of the publishing company to invite the staff of the company over its lead story on Sunday Trust publication, which divulged classified military information, thus undermining national security.
"In it, the newspaper disclosed details of planned military operations against the Boko Haram terrorists. The disclosure of classified security information amounts to a breach of national security and run contrary to Sections 1 and 2 of the Official Secrets Act. It afforded the Boko Haram terrorists prior notice of our plans and giving them early warning to prepare against the Nigerian military, thus sabotaging the planned operations and putting the lives of troops in imminent and clear danger.
"We would like to state that the invitation of those responsible for divulging military plans was done with the best of intention in order to make them realise the import of such acts to our national security. We therefore advise all, particularly journalists, not to worry but engage in their responsive reportage and to be professional as the Nigerian Army has no intention of muzzling the press or jeopardising press freedom.
"We however, wish to enjoin further that they should eschew jeopardizing national security in their reportage. We would not tolerate situation where a publication would consistently side with terrorists and undermine our national institutions.
"We wish to appeal to all, especially the media, to join hands with the Nigerian military and security forces to end terrorism and insurgency in Nigeria. We would like to further assure that the invitation is for further investigation and if need be, all those culpable of jeopardising operations security will be prosecuted by the relevant law enforcement agency."
