Here in Afghanistan, people are taking this very seriously. Just a few hours ago there were rowdy scenes in the Afghan parliament with many parliamentarians protesting at what appears to be a large loss of lives of Afghan civilians.

Ultimately, the international community and the Afghan government need to win over ordinary Afghans. Every time there is an incident like this, it sets back the whole agenda.

So it's a very dangerous, problematic step for the international community and something the international forces will be desperate to avoid in the future.
