The gang blew up part of the track before boarding the train and marching through the carriages. Witnesses said they saw the men leading passengers into the bush. As mentioned in many previous newsletters, northern Nigeria has been plagued by armed gangs - known locally as bandits - kidnapping people for ransom.

Frustrated and angry, the families of people killed in Lebanon’s catastrophic port explosion today marked 20 months since the blast with a march through the capital Beirut.

At least 216 people were killed and 6,500 wounded in the explosion.
