Men dressed as women were among the attackers who massacred shoppers at a mall in Kenya, it has been claimed.
A government minister said that the terrorists who attacked the shopping complex in Nairobi were all men, but added that some were dressed as women.
Earlier, a white woman wearing a veil was reportedly spotted shouting orders to gunmen in Arabic during the attack on the Westgate complex in the Kenyan capital.
Some reports linked Samantha Lewthwaite, the English widow of 7/7 bomber Jermaine Lindsay, and the attack.
She is wanted by Kenyan police over links to a suspected terrorist cell.
However the Foreign Office later said it was not linking the two.
Sky News' Chief Correspondent Stuart Ramsay said: "I saw a picture of a white woman wearing a balaclava and carrying a weapon."
Security sources say the group of attackers are from several different countries.
A commander of the group believed to be behind the attack has reportedly denied that any of militants are from the UK or US.
