Both Ranariddh and Rainsy protested against the election results, claiming that the CPP-led government had intimidated voters and tampered with ballot boxes. They filed petitions with the National Election Commission (NEC) and Constitutional Court; when these were rejected in August 1998, Ranariddh and Rainsy organised street protests to demand that Hun Sen relinquish power. The government responded on 7 September 1998, by banning street protests and cracking down on participants. At this point Sihanouk intervened, and arranged a summit meeting on 24 September 1998 in Siem Reap. He summoned Hun Sen, Ranariddh and Rainsy for discussions aimed at ending the political impasse. On the day of the summit meeting, a B40 rocket was fired from an RPG-2 rocket launcher at the direction of Hun Sen's motorcade, who was travelling en route to Siem Reap. The rocket missed the motorcade, and Hun Sen escaped unhurt. The police accused FUNCINPEC and SRP leaders of plotting the attack, with Rainsy as its ringleader. Both Ranariddh and Rainsy denied any involvement, but fled to Bangkok the following day, fearing government crackdowns on their parties.
