Ghanaian Foreign Minister Samuel Okudzeto Ablakwa demanded arrests and prosecutions over the killings of two Ghanaian nationals in South Africa as a flight in the latest phase of a voluntary repatriation operation landed in Accra on Monday.

Ghanaian citizens arrived at Accra International Airport before sitting down for a welcoming ceremony and holding a minute's silence for those killed in the ongoing anti-migrant protests across South Africa.

"We have written to the South African authorities that the killing of the two Ghanaians, Mr Bashiru Isak and Mr Kojo Antwi, must not be covered up. There has to be justice, and we will continue to demand thorough investigations, arrests and the prosecution of those who killed our two beloved compatriots."

He said Accra would continue talks with Pretoria but urged South African authorities to rein in those behind the violence.

"We hope that they will also do better in managing this crisis, reining in those who are running amok, attacking people, killing, and looting shops. That is not the kind of Africa that we deserve. These xenophobic attacks cast a very bad image of our continent."

The latest evacuation follows weeks of anti-migrant protests and attacks in South Africa, where campaigners have blamed foreign nationals for crime and unemployment.

Ghana says Bashiru Isak and Kojo Antwi were killed in separate incidents during the unrest.

Isak's body was returned to Ghana earlier this month, while arrangements are still being made to repatriate Antwi's remains.

The government says about 1,000 Ghanaians registered for the latest evacuation phase after more than 900 were brought home during earlier flights in May and June.
