JOHANNESBURG - Nigerian authorities remain on high alert after yet another attack believed to be orchestrated by Boko Haram militants.

On Wednesday, gunmen killed more than 50 people in three villages including near Chibok, the Nigerian town where the group kidnapped nearly 300 schoolgirls last month.

Two days ago twin car bombings claimed 118 lives in the central city of Jos.

No arrests have been made.

The issue was once again debated in the white house on Wednesday with Foreign Affairs Committee chair Ed Royce saying it's critical that the US helps Nigeria.

"It is a struggle for the Nigerian military to cope with this threat and that's lead some to say that we should not get involved but it tells me otherwise. It tells me that US involvement is critical. US forces are well positioned to advise and assist."
