North Korean table tennis officials became agitated on Monday when South Korean reporters took photos of their players practicing at the ExCeL South Arena near the London Olympic Park on Monday.

Even though an official from the London Olympics' organizing committee explained that the area is open to media coverage, North Korean coaching staff shouted, "Do you not understand Korean? We won't put up with this!"
