Two bombs hidden in a truck and minibus have exploded in a crowded market in the Nigerian city of Jos, according to the military. Dozens of people have been killed in the attacks, which could be heard miles away.
"The first IED (improvised explosive device) was in a truck. The second was in a minibus," Kingsle Egbo, a local military official, told the AFP news agency.
"The market was really crowded," he added.
Police said at least 46 people were killed in the blasts, and a further 45 were injured.
"For now, we can authoritatively confirm that 46 people were killed in the blasts while 45 people were seriously injured," said Chris Olakpe, the police commissioner of Plateau state, where Jos is located. "The place has been cordoned off. Nobody should go there until we finish sweeping the place tomorrow (Wednesday)."
Plateau state lies in Nigeria's middle belt region, which separates the country's predominantly Muslim north and Christian south.
The blasts, which Major General Dave Enetie said occurred at the Jos Main Market between a railway terminus and Jos University Teaching hospital, were audible from miles away. The explosions happened approximately 15 minutes apart, shattering windows and flinging rubble into the street.
In April, two separate bomb blasts in the capital, Abuja, killed 120 people and wounded a further 200. Some 25 people were killed by a suicide car bomber on Monday in northern Kano.
There was no immediate claim of responsibility for Tuesday's blasts, but Nigeria has been struggling to curb a bombing campaign by the Islamist militant group Boko Haram.
Earlier on Tuesday, Nigerian diplomats asked the UN Security Council to impose sanctions on Boko Haram following the group's abduction of nearly 300 schoolgirls.
