Africa News Tonight: Call for new Sudan peace talks, US rate cut boosts world markets, Zimbabwe drought may lead to elephant cull

U.S. Secretary of State Anthony Blinken says both sides in Sudan’s conflict must come to the negotiating table to work on implementing agreements to stop their brutal fight. World financial markets got a boost today after the U.S. Federal Reserve on Wednesday cut its benchmark interest rate by an unusually large half-point. Zimbabwe's government says it is considering a proposal to cull its elephant population to address food shortages and reduce the effects of a drought, but some conservationists are pushing back.
