The claim that Malema stated that neither Zimbabweans nor Nigerians in South Africa own the land is not directly found in the provided evidence. However, the evidence does show Malema making statements regarding specific groups (Zimbabweans) and the general issue of land ownership, suggesting the claim is derived from a specific source not fully captured, making it difficult to corroborate with the given evidence. Since the specific quote is missing, it cannot be corroborated.

The evidence provides general information about xenophobia and protests, but none of the provided web search results or Wikipedia entries contain the specific warning that Malema stated anti-migrant protesters might eventually turn on South Africans who do not speak Zulu. This specific warning cannot be verified.

One web search result mentions the anti-migrant movement blocking foreigners from healthcare, and another mentions the anti-migrant movement, but none of the provided evidence explicitly state that Malema criticized the movement for demanding the removal of foreign children from schools and pregnant women from clinics. This specific criticism is not corroborated.
