A training session for the Senegalese women's basketball team in the US has been scrapped, with the West African nation's prime minister saying he cancelled it because some of the squad were denied US visas.

Prime Minister Ousmane Sonko said the team would now train in Senegal's capital, Dakar, "in a sovereign and conducive setting".

It comes amid reports that the US plans to impose fresh travel restrictions on 25 more African countries, including Senegal.

Earlier this month the US announced a ban on citizens from 12 countries, including seven from Africa. There were also partial travel restrictions on nationals from a further seven countries, with three from Africa.

It remains unclear why the Senegalese athletes were denied visas, as the US Embassy is yet to publicly comment on the matter.
