Demonstrations
On Friday July 31, 1987, the demonstration by Iranian pilgrims against the "enemies of Islam" (including the U.S. and Israel), started amid heightened security. The march was uneventful until towards the end of the planned route, where the demonstrators found their way blocked by Saudi riot police and National Guardsmen. At this point, some of the Iranians began to call for the demonstrations to press ahead and continue to the Great Mosque. While this was happening, unidentified persons began harassing the Iranian pilgrims by throwing bricks and other objects at them from a nearby location. These factors exacerbated the situation, escalating it into a violent clash between the Iranian pilgrims and Saudi security, with the Saudis reportedly using truncheons and electric prods and the Iranians using knives and clubs.
Saudi security personnel reportedly opened fire on the demonstrators, a charge which Saudi officials deny. The rioting, and the resulting stampede caused a reported 402 dead (275 Iranians, 85 Saudis including policemen, and 42 pilgrims from other countries) and 649 wounded (303 Iranians, 145 Saudis and 201 other nationals).
The details of the riot are controversial. Iranian officials maintain that the Saudis had fired on the protesters without provocation, and that the demonstrations had been peaceful. Saudi officials insist that no shots were fired, and that all deaths were caused by the melee and stampede.
