He was later posted to Nigeria as an international correspondent, where he won a Peabody Award for his work covering the kidnapping of the Nigerian schoolgirls by the terrorist group Boko Haram.

[7][8] During his assignment in Nigeria, Duthiers reported on the terrorist activities of Boko Haram which, in addition to the kidnapping of the Chibok girls, have been responsible for killing thousands of Nigerians since 2009.

While in the region, Duthiers covered the ongoing military intervention in Mali,[9] the terrorist attack and the In Amenas hostage crisis in Algeria,[10] the trial and sentencing of the former Liberian warlord Charles Taylor at the ICC in Sierra Leone, the crash of Dana Air Flight 992,[11] and President Barack Obama's visit to Senegal.

[12] He also reported from Japan[13] and South Korea on U.S. military operations in the Asia-Pacific theater,[14] in the Middle East on the front lines of the Israeli-Palestinian crisis,[15] from the streets of Bangkok during Thailand's political turmoil[16] and the birth of the royal baby Prince George in July 2013.

He was inspired, he said, by the words often attributed to Saint Augustine: “The key to immortality is first living a life worth remembering.” Duthiers also defended journalism as a profession that gives voice to the powerless and memorializes those who would otherwise be forgotten.
