Authorities charge four men over Kenya's shopping mall attack

Four people have been charged over the terrorist attack on Westgate Mall in Kenya, which killed 67 people.

Charges against the four Somali nationals include harbouring a fugitive and illegally registering as a Kenyan.

Mohamed Ahmed Abdi, Liban Abdulla Omar, Hussein Hassan Mustafah, and Aden Abdikadir Ibrahim – have been imprisoned until a court hearing next week.

Authorities have detained dozens of people since the four-day mall siege, but had not said any suspects were directly related to the attack. It’s unclear how many arrests have been made.

The Somali militant group al-Shabab claimed responsibility for the attack and said it was in retaliation for Kenyan troops’ deployment in southern Somalia.
