Witnesses reported seeing a 'young girl' approaching the station in the Yobe state capital Damaturu around 7:00 am and refusing to be searched by security guards at the gate before blowing herself up.
Reports said the bomber was aged around 12. The attack came just hours after United Nations chief Ban Ki moon wrapped up two day a visit to Africa's largest economy during which he hailed its 'greater stability and peace' under its new leader as he commemorated a deadly 2011 attack on the global body by Boko Haram militants.
"There were two suicide blasts in Damaturu. The first one happened outside the motor park and the second one occurred in Pompomari on the outskirts of Damaturu. But only the bomber has died in the second blast," said Toyin Gbadegesin, a spokesman for Yobe state police.
In the first blast outside the motor park six people were killed and 42 others injured by a female suicide bomber. The injured are receiving treatment in hospital.
Boko Haram has stepped up attacks in Yobe and two other states in its northeastern bastion since President Muhammadu Buhari came to power on May 29 amid a wave of optimism that he could tackle the worsening security situation.
The Islamists have also carried out deadly ambushes across Nigeria's borders and in recent weeks suicide bombers, many of them women, have staged several attacks in Nigeria.
