LUSAKA: Ten Ethiopians are believed to have drowned after a canoe carrying migrants capsized attempting to illegally cross the Zambezi River from Zambia into Botswana, Zambian officials said Wednesday. Migrants often use rivers to bypass official border posts across southern Africa. An AFP report documented migrants crossing the crocodile-infested Limpopo River from Zimbabwe into South Africa on makeshift rafts. The Zambezi is Africa’s fourth-longest river and flows through or along the borders of Zambia, Angola, Namibia, Botswana, Zimbabwe and Mozambique.
