Maiduguri - At least seven people were killed on Tuesday when a car bomb exploded in Nigeria's northeastern city of Maiduguri, a witness said, the latest violence in a region beset by an Islamist insurgency.
People splattered with blood tried to flee as a second car was ignited by the explosion in Maiduguri and soldiers started firing automatic rifles.
Vehicles smashed into each other as drivers hastened to escape.
A suicide bomber is suspected in the lunchtime Tuesday blast. Maiduguri is the birthplace of the Boko Haram extremist network that has been terrorizing northeast Nigeria.
