Experts from the US, UK and Interpol have joined their Kenyan counterparts during the investigation into a four-day siege on the Westgate shopping centre by Islamist militants in the Kenyan capital Nairobi.
Interior Minister Joseph Ole Lenku was unable to confirm the nationalities of those involved and said work to establish the identity of the terrorists is ongoing.
He said: "In our previous briefings we indicated that there was no indication to suggest that there is a woman terrorist but going forward we are all hearing possibilities and information."
