Democracy can be a messy business. And as you can see from this video, the Afghan Parliament is no exception.
Video of a parliamentary session posted by Tolotv shows Nazifa Zaki, formerly a general in the army, throw a shoe at fellow MP Hamida Ahmadzai. Zaki then rushes across the aisle to attack Ahmadzai, who throws a water bottle in apparent self-defense, and the ensuing tussle is quickly broken up:
CNN reports that a coalition requested President Karzai appear to discuss recent rocket and artillery attacks from Pakistan.
Ahmadzai specifically wanted to summon two vice presidents on this issue. That's is what set off Zaki.
