Inside the Afghan attack on the UN compound

Officials are painting the weekend killings at the United Nations mission in northern Afghanistan’s largest city—which sparked cascading violence across the nation—as the handiwork of a small band of insurgents that used a protest against a Quran-burning as cover for a murderous plot.

But a Wall Street Journal reconstruction of Friday’s assault, based on unreleased videos, interviews with demonstrators and the U.N.’s own recounting of events, shows a more complex picture and indicates that ordinary Afghan demonstrators played a critical role in the attack…

Inside the building, other attackers targeted one of the safe rooms. The door proved little protection against the mob. As intruders penetrated the safe room, Pavel Ershov, a Russian diplomat who speaks fluent Dari sought to protect three staff members by distracting the assailants, the U.N.’s Mr. de Mistura said.

“Are you Muslim?” the assailants asked Mr. Ershov, according to one diplomat briefed on the attack. Mr. Ershov lied and said he was, the U.N. said. The assailants tested him by asking him to recite the traditional profession of belief in Islam, which begins, “There is no God but Allah.”

When he successfully completed the test, his life was spared. Still, he was dragged into the street and beaten badly, according to a local shopkeeper who said he participated in the assault.
