Nigeria - 4 Are Killed by Gunmen - NYTimes.com Gunmen fatally shot four people at a gas station on Wednesday in the northeast Nigerian town of Potiskum, where the day before suspected members of the Islamist group Boko Haram shot dead eight people at a bar. Boko Haram's increasingly violent insurgency has become a major security problem for President Goodluck Jonathan's administration, also facing pressure from nationwide strikes and protests against fuel price increases. "Four people were shot dead this afternoon, but I cannot confirm whether the attackers were Boko Haram," said Tanko Lawal, the police commander in Yobe State.
