Four charged over Westgate siege

[Jimbuna]

None of the four are accused of being in the shopping centre but have been charged with aiding the four (it is believed) gunmen who carried out the atrocity.

Four people have been charged over the siege at the Westgate shopping centre in Kenya's capital, Nairobi, in which 67 people were killed, police say.
The four foreigners have been charged with aiding terrorist groups and being in Kenya illegally.
Their nationalities have not been disclosed, but they are said to be ethnic Somalis.

Did we ever learn just who or how many attackers there were?

It is believed there were four but I've no idea how accurate the estimation is.
