Mexico was rocked by a violent rampage this week, after the drug lord, El Mencho, died following a fire-fight between his bodyguards and Mexican military commandos. It’s stark evidence of the challenges facing President Claudia Sheinbaum as she vows to take on the country’s criminal gangs. Quentin Sommerville reports on the fallout following El Mencho's death and the disturbingly deadly rivalry between the cartels.

While Benin has only a handful of highways, its lush inter-connected lagoons provide a vital commercial artery. Sara Wheeler took a trip down the Black River.
