The Nigerian military on Tuesday said it has recovered a Boko Haram hit list, which contains names of communities targeted by the extremist group.
The Defence Headquarters through its official Twitter page said other documents, including sketches of towns, were also recovered.
Boko Haram militants have overrun several communities in northeast Nigeria, killing residents and destroying their homes and places of worship.
The military has, in recent weeks, reclaimed some towns that fell to the terrorists.
In two separate operations spanning Adamawa and Bauchi states, government troops killed 27 suspected terrorists during fighting, defence spokesperson, Chris Olukolade, was quoted as by PRNigeria as saying.
