Nigeria witnesses deadly stampedes in recent months

In March, two students died and at least 23 people were injured after being crushed by a big crowd that had gathered to collect free bags of rice.

Also that month, at least four people were crushed to death at another place where they were meant to collect cash gifts that would help them pay for food.
