Three bomb attacks blamed on a feared radical sect killed one person and wounded 11 others in a volatile central Nigerian city, an official said on Sunday.
The bombs went off at about 10 pm (local time) in three spots in Jos where people had gathered to view a televised match between Real Madrid and Barcelona, said Plateau state spokesman Pam Ayuba.
Authorities suspect a radical Muslim sect locally known as Boko Haram which has launched similar simultaneous attacks in northern Nigeria, he said.
The sophistication of these latest attacks, which targeted some 600 people who were drinking while watching the high-profile match, suggests the work of Boko Haram, Ayuba said.
The blast killed a 35-year-old barber, Ayuba said. A fourth bomb was found not detonated in one of the viewing centers, he said.
Of the 11 wounded, nine have been discharged from the a local hospital, authorities said.
The attacks occurred in heavily militarised areas of a city which sits in Nigeria's "middle belt," where dozens of ethnic groups vie for power.
The city has been at the epicenter of religious and ethnic violence in the country, straddling the dividing line between Nigeria's largely Christian south and Muslim north.
The Jos violence, though fractured across religious lines, often has more to do with local politics, economics and rights to grazing lands. The government of Plateau state is controlled by Christian politicians who have blocked Muslims from being legally recognized as citizens.
