The explosions occurred in a camp for refugees having displaced internally about 5 a.m. A local Friday, Nigeria's weapon spokesman, Onyeama Nwachukwu, told CNN. There were no reports of any deaths or injuries.
"The troops attacked this morning in the camp, but the military is currently blocked," said Nwachukwu, adding that the army still assesses the situation.
Simpa Samson's journalist told CNN that the soldiers targeted the Teacher Village camp in the Maiduguri capital of Borno State.
"The military secured the place almost immediately and it has given our foreign film the best of filming, no-one was hurt because the bombs had landed outside the building," Samson told CNN .
Security is often a concern in the city of Maiduguri, which has been a frequent target of the Boko Haram terrorist group. The city also has a large number of uninhabited refugees.
The blasts came because people in Nigeria are ready to submit their vote on Saturday, a week after the presidential and parliamentary elections of the country were suspended unexpectedly just hours before the polling stations opened. This was the third successive vote to be postponed in Africa's largest democracy.
The owner, Muhammadu Buhari, 76, runs against 71 other candidates but his main challenge is Atiku Abubakar, a 72-year-old business tycoon and a former vice president. They are Muslim candidates from the north of the country.
When Buhari, a former military manager, was elected in 2015, this is the first peaceful transfer of power in the country. He promised to be a new cast, offering a clean sweep of the old system but many have been left in good faith and are angry with the levels of inequality and extreme poverty.
Concerns about violence related to election
Last week, a terrorist group with relations with ISIS claimed a responsibility for a deadly assault in Maiduguri on a motor carrier carrying state governor Kashim Shettima.
Shettima came to escape without knowing and said his director of media told Isa Gusau told CNN on Thursday that the robbery kills three people, although the local people set the figures much higher. The terrorist group claimed that 42 people died in the assault.
The terrorist group of the Islamic Islamic State of West Africa, the breach of the military group Boko Haram, has hosted a number of high profile assaults in recent months.
Although people in some parts of the country were registered to vote early on Saturday, others were frustrated as electoral officers had not appeared.
