From a really great TIME piece by Ashraf Khalil :
Ultraconservative Salafist Muslims and other Islamist factions essentially started this fight when—bolstered by several inflammatory television sheikhs—they marshaled a large protest outside the embassy gates on Tuesday evening, coinciding with the anniversary of the Sept. 11 attacks on the U.S.. But having sparked the protests, the Islamists seem to have almost immediately lost control.
By Wednesday evening the clashes had begun—often despite the best efforts of some of the Islamist groups on the scene. On Thursday, I witnessed this dynamic in action as a temporary peace between police and protestors dramatically broke down.
A group of young men suddenly resumed throwing rocks at the police—who largely huddled behind a phalanx of plexiglass shields and made no offensive moves at first. Into this maelstrom stepped an incredibly brave group of bearded men—and one woman wearing the full Saudi-style niqab. Facing down a hail of rocks and yelling for calm, they essentially acted as voluntary human shields for the police. (In a slightly humorous side-drama, the Islamist men repeatedly kept dragging the woman away and yelling at her to stay on the sidelines for her own safety.)
