A Siberian woman was in critical condition in a South African hospital after inadvertently walking into the path of a wounded green mamba, Reuters cited an emergency official as saying today. SAPA news agency reported that the snake, run over by a car at a shopping centre in Kwa-Zulu Natal province, lashed out at the woman as she crossed the street, biting her twice on the leg. "She is critical. The information we have is that she is from Siberia," Netcare 911's Jeff Wicks told Reuters. The green mamba, found in eastern and southern Africa, is generally not an aggressive snake, but will strike if provoked.
