Chinese, Russian and Iranian ships were seen moving into and out of the harbour that serves South Africa's top naval base in Simon's Town, south of Cape Town, where the Indian Ocean meets the Atlantic Ocean. It was not immediately clear if other countries from the BRICS group which also includes Brazil, India and the United Arab Emirates, among others would take part in the drills.
The two-day joint military deployment that kicked off on Sunday is likely to anger China, which claims nearly the entire key waterway and has separate territorial disputes with the two Asian countries.
