Frank Gardner: Nairobi-style terror attack in UK?
The BBC's security correspondent reviewed the terror attacks in Nairobi - with shootings, throwing of grenades, and taking hostages - and pondered if such an attack could happen in a British shopping centre.
Earlier this week, David Cameron chaired an emergency meeting on the Kenyan attack, which included British victims.
Frank Gardner looked at the lessons from Kenya - and also the changing political situation in Iran which is reaching out to the US - and how they could affect the UK and western nations.
