More than 400 Nigerian citizens fleeing the war in Ukraine have returned home after being evacuated by the government, according to the West African country’s Diaspora Commission.

The first batch of returnees arrived in the capital Abuja early Friday from Romania, according to the government agency Nigerians in Diaspora Commission (NIDCOM).

The second batch of evacuees arrived from Poland later Friday while the third batch landed in Abuja close to midnight Friday in a chartered flight from Hungary, NIDCOM said in a series of tweets.

NIDCOM stated Saturday that another flight provided by the Nigerian government had arrived in the Hungarian capital Budapest to evacuate more Nigerians.

Hundreds of international students, many of them Nigerians, remain trapped in their hostels in Sumy, in northeast Ukraine, surrounded by Russian troops and amid explosions and gunfire.

Nigeria’s foreign minister Geoffrey Onyeama said on Thursday that his office was aware of the plight of the stranded students, and that arrangements were being made for their evacuation.
