At least 170 people are killed killed and at least 50 people are injured after an oil tanker explodes close to the western border state some 250 km (155 miles) away from the capital. After the tanker veered off the road and overturned, local residents were siphoning off the fuel when the vehicle exploded. It is suspected that a cigarette might have sparked the explosion. Local hospitals have been overwhelmed, and state officials have appealed to the Red Cross and the UN for help. Doctors and medical staff are flying in from across the country to help with the emergency.
