Two car bombs minutes apart have killed at least 118 people in the central Nigerian city of Jos.
The blasts that happened on Tuesday flattened several buildings, and officials say they are expecting to find more bodies.
The car bombs went off in a busy marketplace, near a bus station and a hospital.
No one has claimed responsibility. But suspicion immediately fell on Boko Haram - the Islamist extremist group blamed for thousands of deaths as it tries to set up a conservative Muslim state in the north.
The group also is behind last month's kidnappings of nearly 300 schoolgirls from a remote village in Borno state.
Nigerian President Goodluck Jonathan calls Tuesday's bombings "cruel and evil," and says he is fully committed to winning the war on terrorism.
Nigerian lawmakers voted Tuesday to extend a state of emergency for six months in the northeast, where Boko Haram is most active.
