Police in Kenya have charged the wife of a medic suspected of planning an anthrax attack and recruiting for the Islamic State group with being a member of a terrorist organization.

Police accuse Nuseiba Mohammed Haji, wife of medical intern Mohammed Ali Abdi, of being an accomplice in a foiled plan by Islamic State-linked extremist medics to launch an anthrax attack in Kenya.

Abdi was arrested in April.

Haji, a medical student who was extradited from Uganda, appeared before a trial magistrate Monday and denied the charges.

Kenya is struggling to battle the Islamic State group's recruitment of some of the country's youths. Police say at least 20 young people have travelled to Libya to join it.
