At least 30 African migrants arrived in Lagos, Nigeria on Thursday after the United Kingdom came to an agreement with Nigerian officials to take people who were being deported from the region.

It was unclear why the African migrants were removed from the United Kingdom but officials reportedly said they broke laws in the U.K.

Among the deportees, 22 were Nigerians. The remaining were Ghanaians who would be transported back to their home country.

The United Kingdom has come to similar migration agreements with other African nations, including Ghana and Rwanda.

Protests were reported outside of a detention center in England for women. Some of those who were deported were mothers and LGBT people, including those who feared returning to their home countries.
