In a statement on Thursday, the militant group, which Boko Haram pledged alliance to two years ago, explained how its members organised the operation.
“The fighters took three four-wheel-drive vehicles and others mounted with rifles and heavy weaponry and various ammunition,” the statement said.
ISIS, however, did not provide evidence for its claim.
Spokesman of 3 division military base in Damaturu, Kayode Ogunsanya, said there was casualty on both sides, but he could not ascertain the number.
“There was casualty on both sides but I cannot ascertain the number. Men on ground had repelled the attack,” Ogunsanya had said.
This is the first time that ISIS will take full responsibility for an attack in Nigeria.
