A fresh string of killings of Nigerian nationals in South Africa is adding to pressure on the diplomatic relationship between the two countries, with at least a dozen Nigerians reported killed since the start of 2026 amid a renewed wave of xenophobic violence, according to a report by Guardian Nigeria. The most recent deaths occurred across a span of days in September, bringing the toll for the year into double digits.

Among the recent cases, one Nigerian man died after jumping while attempting to flee what was described as police harassment in Bloemfontein, and a Nigerian security guard was shot in Pretoria following a dispute over a bar cup. Advocacy groups tracking the killings say law enforcement officers have been linked to a significant share of the deaths recorded since the latest wave of violence began earlier in the year, rather than the attacks being confined to vigilante or mob incidents.

The pattern has reignited long-running frustration in Nigeria over how its citizens are treated in South Africa, a relationship repeatedly strained by episodes of xenophobic violence, allegations tied to crime and economic competition, and a sense in Abuja that previous rounds of diplomatic engagement have done little to change conditions on the ground. Pressure is building on Nigeria's government to move beyond routine diplomatic protest toward a firmer response on behalf of its citizens.
