JOS, Nigeria -- A bungled bomb killed three people, including a suicide bomber, in Nigeria's Jos city Saturday night, a police official said, four days after twin car bombs blamed on Islamic extremists killed at least 130 people in the central city.
The senior police official said the bomber dropped a bag holding explosives at an outdoor theater crowded with people watching a European soccer cup final. He said the bomber and two others died. The official spoke on condition of anonymity because he is not the official spokesman.
The venue is not far from the bustling marketplace that was targeted in Tuesday's attack.
There were no immediate claims of responsibility for the latest attack.
But the Islamic extremist group Boko Haram, which has been threatening to sell nearly 300 abducted schoolgirls into slavery, has been waging a two-pronged campaign of urban bombings and rural attacks on northeastern villages.
Separate car bombs in April killed about 100 people in Abuja, Nigeria's central capital, and a car bomb that exploded prematurely Monday killed at least 24 people in northern Kano, the country's second most populous city.
The attacks appear to be in defiance of an international campaign to rescue the girls and a commitment made at a summit of Nigeria, its neighbors and Western leaders in Paris a week ago to unite to wage total war on Boko Haram.
Nigeria's President Goodluck Jonathan and his government are confronting national and international outrage at their failure to rescue the abducted girls.
Thousands have been killed in the 5-year-old Islamic uprising that aims to turn Nigeria into an Islamic state, though the country's population is almost equally divided between a mainly Muslim north and predominantly Christian south.
Jos sits on a fault line where the two regions meet, and the attacks are seen as an attempt to ignite religious rivalries that have erupted with deadly frequency, though the city had been peaceful until recently.
