Blowback Terrorist Attack at Nairobi Shopping Mall

The BBC reports:

A gun battle inside a shopping centre in the Kenyan capital Nairobi has left at least 20 people dead, the Kenyan Red Cross says.

The gunmen attacked the Westgate centre - one of the city's most exclusive. Dozens of shoppers fled; many are still feared trapped inside.

Police originally said it might be an attempted robbery but are now treating it as a terrorist attack.

The Somali militant group al-Shabab had threatened to strike the centre.

It is opposed to Kenya sending troops to fight in Somalia.
