The South African Zionist Federation has submitted a complaint to Pretoria’s Department of International Relations and Cooperation, arguing that the plan to name a Johannesburg street after Palestinian plane hijacker Leila Khaled violates both domestic and international law.

The proposal to rename the city’s Sandton Drive, which is home to the U.S. consulate, to Leila Khaled Drive amounts to “a diplomatic insult that could have far-reaching consequences for South Africa’s international relations and investment,” the group wrote.

Under S.A.’s Diplomatic Immunities and Privileges Act, the country has a “duty to take all appropriate steps to protect all consular premises, including that of the USA, and prevent the impairment of their dignity,” the group noted, adding that this is also a “principle of international law.”
