Zambian authorities on Sunday said they had arrested three Chinese nationals and two locals found carrying pieces of rhino horn at the border with Mozambique. Parks and wildlife ministry spokesman Sakabilo Kalembwe said the five were arrested at the Chanida border post. On Wednesday a 24-year-old Chinese woman flying from Zambia with 20 kilograms of rhino horn was arrested at South Africa's main airport on her way to Hong Kong.
