really unusual. a spokesperson for the taliban saying it certainly wasn't them. so questions being raised as to who was responsible for this massive suicide car bombing in the center of kabul. which as you say has claimed the lives of 12 people, three of those being u.s. contractors who were working for the coalition forces over there in afghanistan. remember, there are only 10,000 u.s. forces still in country at the moment. and u.s. contractors are still working with the coalition. this is the biggest loss of american life in one incident in afghanistan this year. and i should also mention that more than 60 for wounded. and as you say it took place outside a clinic, this private hospital where people go to see doctors. they were queueing up outside. also it was rush hour, so hence the number of casualties, the number of civilians.
