Car bomb kills civilians in Kabul

A car bomb has killed at least three people and wounded two in Afghanistan's capital, Kabul.

It was an apparent attack on a foreign contractor company but Interior Ministry spokesman, Najib Danesh said all those killed and wounded in the explosion were civilians.

While the latest blast was relatively minor compared with others that have killed scores of people recently, the constant

stream of attacks in Kabul has undermined confidence in the Western-backed government of President Ashraf Ghani.

Earlier this week, General John Nicholson, the top U.S. Commander in Afghanistan, said security in Kabul would be "the

main effort" for international powers helping Afghan defence and security forces.
