Two car bombs exploded in Nigeria's central city of Jos on Tuesday, killing at least 118 local civilians.
One ripped through the center of a busy market, another, half an hour later, outside a nearby hospital, killing some rescue workers.
A local official says the death toll could rise further as rescue teams continue to recover bodies from the smoldering debris.
It's not yet clear who's responsible for the attack, but Boko Haram is the prime suspect.
The militant group has been carrying out a series of bomb attacks across the center of Nigeria, trying to overthrow the government and create an Islamic state.
If Boko Harem is to blame, Tuesday's double bomb blast would make it their deadliest single attack in five years.
President Goodluck Jonathan issued a statement late Tuesday expressing sympathy for the victims, and reassuring the public that the government remains committed to winning the war against terror.
Terrorism in Nigeria has been under the international spotlight ever since Boko Haram kidnapped more than 200 schoolgirls back in mid-April.
The girls who remain unaccounted for are reportedly being threatened to be auctioned off to become wives of militants.
The campaign to get those girls back continues in Nigeria.
"There is hope, there is a lot of hope, we believe the girls are safe, we believe the girls are alive, and we believe with the tremendous support the Nigerian military is getting, we believe the girls will be rescued and returned home."
But fear is rising.
As evident by this latest attack, Boko Haram is becoming increasingly vicious in their campaign for an Islamic state.
More than one-thousand people are believed to have been killed by the militant group this year.
