While other sources confirm deaths, the specific claim that 'South African police say two people from Mozambique were killed' is not explicitly corroborated by the provided web results; one result mentions police confirmed 'two deaths in Mossel Bay' but does not explicitly specify they were Mozambican in the snippet provided, though it is in the context of Mozambican fatalities. However, the provided evidence for claim 5 specifically consists of irrelevant search results (US South, Southwest Airlines), meaning the evidence provided in the 'Evidence for claim 5' section is useless. Looking at the evidence for claim 4, it mentions police confirmed two deaths in Mossel Bay, but doesn't explicitly link them to Mozambique in that specific sentence. Therefore, it lacks strong independent corroboration of the police's specific attribution.

This claim is only mentioned in the France24 cross-reference. No other provided evidence corroborates the specific number of 500 people fleeing on Monday.
