A first group of 415 Nigerians who fled the Russian invasion of Ukraine were repatriated to their country on Friday, AFP journalists noted at the airport in the capital Abuja.
The group, mostly students, arrived in Abuja around 7:30 a.m. (0630 GMT) from Bucharest, the capital of Romania, one of the countries where many African students have fled.
The Nigerian nationals arrived with tired faces but looking relieved.
"I am very happy to be back home, thank you Nigeria," exclaimed a young woman on the airport tarmac.
Several students, most still dressed in their winter clothes, recounted their traumatic experience.
Oyewo Elisha, 22, who was studying in Kharkov, immediately mentioned "heavy artillery, missiles, bombs and all that."
"Everywhere, it was really terrible. Nobody could stay there, it was really dangerous."
Haroun Rukayat, 20, explained that she had to wait 14 hours in the cold before she could enter Romania.
"I am one of the lucky ones who managed to get out. For now, some people are still stuck in different cities, especially in Soumy where the war is raging," she insisted.
"I am grateful and I thank God for protecting me."
The government of Nigeria, Africa's most populous country, has chartered three planes from local companies Max Air and Airpeace to Europe to repatriate more than 1,000 people.

Many African countries are stepping up efforts to help their nationals who have flocked to Poland and Romania in particular, against a backdrop of accusations of racism at Ukraine's borders.
