New Delhi, Oct. 15 -- A group of 14 people have become the latest West Africans deported from the U.S. to Ghana under an accord between the countries, said a lawyer whose group filed a lawsuit Tuesday seeking to block the arrangement.

Oliver Barker-Vormawor, who represents migrants, said the latest group of 14 West African nationals arrived Monday to bring the overall total to 42 deportees accepted by the Ghanaian government.

His group, Democracy Hub, filed a lawsuit Tuesday against Ghana 's government, alleging that the agreement with Washington is unconstitutional because it wasn't approved by the Ghanaian parliament and that it may violate conventions that forbid sending people to countries where they could face persecution.
