In October last year, a fuel tanker explosion killed 153 people in Jigawa state, north-west Nigeria. In January this year, a truck carrying about 60,000 litres of petrol overturned near Suleja, also in Niger state, killing at least 86 people and injuring nearly 70 others.

Demonstrations for the release of a separatist leader in Nigeria’s capital city turned violent on Monday as police fired tear gas and arrested dozens of protesters.
