A police woman attached to a polling unit has been reportedly killed and seven others seriously injured in northeast Nigeria's Borno State when a bomb blast exploded during the ongoing parliamentary elections.
A Xinhua reporter based in Maiduguri said more people were feared killed, noting that the bomb exploded minutes after the voting accreditation ended at the Angwa Doki polling unit.
He said an official of the Independent National Electoral Commission (INEC), security officials and electorates were among the victims of the deadly bomb blast.
The reporter said there is panic in the entire state as eligible voters have vacated the polling unit following the bomb blast.
Security officials in the state did not respond to calls and text messages when contacted.
In another violent incident, 13 people were killed and 26 injured on Friday after an electoral commission office in Suleja, Niger State was hit by an explosion.
Saturday's bomb attack came at a time when serial killings by suspected members of the sect group Boko Haram, continued in Borno.
Meanwhile, on Saturday, unknown armed men shot and killed an official of the All Nigeria People Party (ANPP) and his son in Jere local government area in northeast Nigeria's Borno State.
"Unknown gunmen invaded Fannami Garnam Bula-Bulin residence around 1:00 a.m. local time and fired several shots at him in his bedroom," Malam Zanna
Abubakar, a relative said.
More than 50 other people, mostly security personnel, had so far been killed by suspected Boko Haram militants since July 2009, when they launched attacks on individuals. The Boko Haram launched the first attack in the state in July 2009, during which many were killed and wounded with properties destroyed.
The sect's leader Mohammed Yusuf and his alleged financier Buji Foi were killed in a counter attack by the security operative.
Members of the sect staged an uprising in Maiduguri in 2009, attacking symbols of the government authority including prisons, police stations and
schools, leading to clashes with security forces in which an estimated hundreds of people were killed.
