text: For three years after the incident of 1987 -- from 1988 to 1990 -- the Iranian government banned Iranians from going on the Hajj  but "diplomatic ties were restored in 1991".
  Following the incident, Saudi Arabia ended its diplomatic relations with Iran and it reduced the number of permitted Iranian pilgrims to 45,000, down from 150,000 in earlier years. In 1991, Iran and Saudi Arabia renewed diplomatic relations after agreeing to allow Iranian pilgrims to perform the Hajj once more. The total number of pilgrims was set at 115,000, and the demonstrations by Iranians were again allowed, but only in one specific location granted by the Saudis. By this agreement, Iranian pilgrims continued their annual demonstration during the 1990s and 2000s with few or no incidents. They limited their rally to within the confines of their compound in Mecca.
  Approximately 20,000 Pakistani troops who were stationed in Saudi Arabia were sent back to Pakistan, because Saudi Arabia was uncomfortable with the presence of Shi'ite soldiers.
  Martin Kramer writes that "as no independent investigation will ever be conducted, important details will remain in doubt. But no evidence has been produced by Saudi Arabia or Iran to establish that the other side acted deliberately or with premeditation in order to provoke violence."
