Three people were killed in northern Nigeria when a woman blew herself up as customers were waiting in line to buy cooking oil on Monday, the Associated Press reported.
Witnesses said the female suicide bomber was dressed in traditional Nigerian clothing and in line with other women at the petrol station in Kano city when the attack occurred.
"I was nearby the queue when I heard a heavy loud (noise)," Tijjani Isa, an employee at the patrol station, told the AP. "And immediately saw people running while others went down."
Ten people were rushed to the hospital after the bombing, three of whom later died, Kano police spokesman Musa Magaji Majia told AFP.
The bomber armed herself with "a low-caliber explosive, which is why the casualties were minimal," the spokesman said.
Monday's attack happened just one day after another attack involving a female suicide bomber, who was 15-years-old, occurred in the same city. The teenager was the only victim in the attack near a temporary university site, Kano State Police Commissioner Adernele Shinaba told the AP.
Also on Sunday, five people were killed after a bomb detonated at a Catholic Church, prompting Kano officials to cancel all public religious celebrations in the city, including the Eid celebration marking the end of the holy month of Ramadan.
The Islamist militant group Boko Haram, which has killed thousands in attacks throughout the north, has not claimed responsibility for the attack. But Kano has been targeted by Boko Haram in the past.
Monday's attack could indicate the militants are seeking to expand their operations in the rural northeast by attacking key urban areas, AFP reported. The group wants to form an Islamic state in the country's Muslim majority north.
Suicide attacks involving women rarely occur in Nigeria. But such attacks appear to have increased ever since Boko Haram kidnapped early 300 schoolgirls from their boarding school in April, the AP reported.
