Christians are not being killed in Sudan. Those making such claims lack a basic understanding of geopolitics. In reality, Muslims are the ones being killed, particularly the Masalit Muslims, who are being targeted primarily because of their race. They are being oppressed and targeted more than anyone else.
In Nigeria, both Muslims and Christians are being attacked by Boko Haram and other ISIS-affiliated extremist groups. However, these groups disproportionately target Christians.
These ISIS-affiliated groups have been created or supported by the CIA and Mossad, but regardless of their origins, they are extremist organizations.
