Safety in Warri Nigeria (Bangalore)

Dear Members,
Let me introduce myself as Dr. Aemen Asher, I am presently residing in Kerala India. well I have got a job offer in Warri Nigeria at The Lily Hospital. The deal is good as Am being covered under the UNDP(United Nations) umbrella.
But my major concern is about the safety issues in the locality, as I am planning to relocate with my family.
Could anyone of you please pour in your reviewes/suggestions.
