This view was expressed on Tuesday at the US Department of States' daily briefing in Washington.
The US government also said that the recent incessant attacks by the Boko Haram insurgents could be as a result of the approaching general elections in Nigeria.
"There has been a sharp escalation in the number of reported casualties. I think the numbers tend to be from about 2009 to 2013 – there were a little over 1,000 casualties. I mean, we've obviously all seen the reported numbers just this week – which we can't confirm exactly, but it clearly shows there's been a sharp escalation.
"It's because Boko Haram has tended to, particularly around something like an election, used political issues or sensitivities to try and inflame tensions. We've seen that as one of their tactics, and that's why it's so important to move forward with the election, because we believe it's important. Well, I don't want to prejudge.
"We've seen successful elections go forward in places that have pretty significant levels of violence. So, we believe the election should go forward. We know there are security challenges. We do think that the election is probably a factor. As I said, we believe the election should still go forward, even in the face of this pretty horrific violence," Marie Harf, the US spokeswoman, told journalists.
According to her, the US government will continue to assist President Goodluck Jonathan's administration in fighting terrorism, despite the fact that a training programme by the US for Nigeria's military personnel was cancelled by Nigeria late last year.
