The Ethiopian government has scrapped visas-on-arrival for Nigerians with immediate effect.

In a statement, the government said travelers would need to obtain their visas at its embassy in Abuja before embarking on any trip to the country.

The development comes barely two weeks after Ethiopian Airlines emerged as the core investor in Nigeria Air - the country’s national carrier - with 49 percent shareholding.

The embassy did not say what prompted the decision to cancel visa-on-arrival for the Nigerians.

It, however, said the new policy did not affect passengers transiting overnight in Addis Ababa.

Ethiopia also mandated Nigerians entering its country and 42 other African countries to produce their yellow fever vaccination cards at any of its borders.

The countries include Angola, Benin, Burkina Faso, Burundi, Cameroon, Central Africa Republic, Chad, Cote d’Ivoire, Congo, Democratic Republic of Congo, Equatorial Guinea, Ghana, Kenya, Liberia, Mauritania and Niger.

Others are Rwanda, Senegal, Sierra Leone, Sudan, Togo, South Sudan, Uganda, Argentina, Bolivia, Brazil, Columbia, Ecuador, French Guyana, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago and Venezuela.
