Isa Gusau, a media aide for Shettima, told CNN on Thursday that security agencies were investigating the attack that he said killed three people. The terror group claimed that 42 people died in the assault.
Militants ambushed the governor to attract media attention and spread its “propaganda strategy,” Gusau said.
“They (Boko Haram) feed on publicity and they did that to generate attention. So far only three died,” Gusau said.
Nigerian President Muhammadu Buhari has been criticized for failing to deliver on his campaign promises to end the years-long insurgency that has left thousands displaced in the northeastern part of the West African nation.
Buhari told CNN on Wednesday his government was doing its best to fight Boko Haram.
But he conceded that the group was engaging in new tactics to unleash terror in affected areas.
