The administration of U.S. President Donald Trump has expanded its deportations of immigrants to third countries over the past week and a half, sending Cuban, Venezuelan, Nicaraguan, Afghan, Iranian, Nepali, and Turkish nationals to African nations, according to documents obtained by NBC News.

The material shows that over the last 10 days, Washington dispatched more than 100 immigrants aboard three U.S. Immigration and Customs Enforcement (ICE) flights to eight African nations: Burundi, Cameroon, the Central African Republic, Equatorial Guinea, Eswatini, Liberia, Rwanda, and Sierra Leone.

Among the individuals on those flights were citizens of certain African nations, but documents show that none of the deportees were sent to their country of origin.

CBS News explains that these deportees included individuals with criminal records in addition to immigration violations, although many lacked any criminal history beyond being undocumented in the United States.

More than 30 countries worldwide have reached agreements to receive third-country immigrants deported by the United States, including Panama, Costa Rica, El Salvador, Ecuador, and Paraguay.

Since returning to the White House in January of last year, Trump has sought such agreements to accelerate deportation numbers, fulfilling one of his key campaign promises.
