Eritrea denounced a U.S. ban on
immigrant visas for its citizens as "unacceptable" on Saturday, while Nigeria's government said it had created a committee to address the issues that prompted U.S. President
Donald Trump to add the country to the ban.
Nigeria and Eritrea were among six countries, four of them in Africa, added to an expanded version of the U.S. visa ban announced on Friday in a presidential proclamation.
U.S. officials said the countries failed to meet U.S. security and information-sharing standards, which necessitated the new restrictions.
