Heightened security is being imposed in Khost and Kandahar in Afghanistan after two Taliban attacks took the lives of 13 Westerners including eight CIA operatives.
A suicide bomber dressed as an Afghan army officer killed the CIA agents who were acting as advisers. The killings have cast doubt on the strategy of mentoring Afghan nationals.
Christine Fair a Georgetown University political analyst said: “They have really become a vehicle of infiltration for the Taliban. This is most certainly a vulnerability in our strategy going forward in trying to hand over security to the Aghans if we don’t really have a way of figuring out who we can trust.”
