The first blast happened at about 7:30 pm near the entrance to the Dadin Kowa terminus, while the second occurred some 20 minutes later in the Dukku area.
Witnesses reported hearing two blasts at both sites but lack of electricity made it impossible to say whether they were suicide attacks or homemade bombs left at the scenes.
Gombe city was hit last Thursday, when a series of improvised explosive devices went off in a market, killing 49.
“So far we have recovered 12 dead bodies from the blast scene,” said one rescue worker, who asked not to be identified, at the first site. “The bodies are badly mutilated and we have several people injured.”Our main focus now is to save lives.”
Gombe state police spokesman Fwaje Attajiri confirmed the blast but did not give a death toll.
Attajiri had no details about the second explosion but one trader, whose shop is near the Dukku bus station, said:
“There were two explosions. They happened after I had closed my shop for the day.“I and others who were around came back and began pulling out bodies. I counted up to 30 dead bodies. I became sick and left.”
