( CNN ) Suicide bombers targeting a bus station in Kano , Nigeria , killed 10 people and left several injured Tuesday , according to the city 's police chief , just hours after a similar attack in Yobe state killed 17 people . Two men detonated the explosives concealed under their clothes as soon as they got off the bus at Kano Line motor park Tuesday afternoon , Police Commissioner Ibrahim Idris said . The busy station is located in the city center of Kano . Idris said the two men took the bus from the town of Wuddil , 30 kilometers ( about 19 miles ) from Kano . `` The bus station was their target , and taking a bus from outside the city gave them easy access into the bus station , '' Idris said , explaining that the men `` would have undergone screening before getting inside if they had come by any other means . '' The attack occurred at 3 p.m. local time , just hours after another suicide attack left 17 people dead , in addition to the bomber , and 27 people injured at a bus station in Potiskum , about 200 miles away in Yobe state . The Potiskum attack occurred at Tashar Dan-Borno motor park on the outskirts of town . A man pretending to be a passenger detonated the explosives as he boarded the bus , which was being loaded and prepared for departure , according to witnesses . An official at the Potiskum motor park said 12 passengers were inside the bus when the bomber , who `` looked to be in a hurry '' came and dropped his luggage in the baggage compartment . The man `` made to enter the bus , but before he could be restrained for routine screening there was an explosion which killed all 12 people inside the bus and the bomber , '' the motor park official said . A paramedic at Potiskum General Hospital , who asked not to be named for fear of reprisals , said four people who were transported from the scene died later . Resident Ahmad Maina , who was at the scene shortly after the blast , said the bus was engulfed in flames as firefighters struggled to keep it from spreading to other vehicles . Although no one has claimed responsibility for either of the attacks , Boko Haram has been behind dozens of suicide and other bombings‎ in northern Nigeria . Potiskum , the commercial hub of Yobe state , has been hit repeatedly in recent months by bombings blamed on the extremist Islamist group . On Sunday , a 7-year-old girl blew herself up outside a cell phone market in the town , killing seven people and injuring 11 . Last month , two suicide bombers killed six people and injured 37 at the same market . Likewise in Kano , northern Nigeria 's most populous city , suicide bombings in the past year have targeted schools , gas stations and a market . Boko Haram 's stated goal is to bring an extreme version of Sharia law to the masses . Along with suicide bombings they have attacked churches and mosques , raided once-peaceful villages and kidnapped people young and old , most infamously more than 200 girls taken last April from a school in Chibok . More than 150,000 people have fled into neighboring countries as a result of the violence , according to the United Nations refugee agency , and Boko Haram has spread its reign of terror into villages and towns beyond Nigeria 's borders . Currently , thousands of Chadian troops are in Cameroon helping that nation 's military root out Boko Haram fighters . Soldiers from Cameroon , Chad take on Boko Haram at Nigerian border .
