Kofi Annan: We have to find a way of reaching out to Boko Haram

Kofi Annan has said force alone may not solve Nigeria's conflict with Boko Haram and that politicians should "reach out" to try to find a solution.

The former UN secretary-general said he hoped whoever wins the Nigerian election will focus on ending the insurgency before it spreads further.

He said the international community can help, but cannot solve Nigeria's problems.
