The massive exodus of Palestinians from Kuwait began with the Iraqi invasion into the country in summer 1990. The exodus included both Kuwaitis and Palestinians, who were forming a large percentage of Kuwaiti residents. Out of initial 350,000 people of Palestinian descent who resided in Kuwait in mid-1990, more than 200,000 fled Kuwait during the Iraqi occupation of Kuwait, due to harassment and intimidation by Iraqi security forces, in addition to getting fired from work by Iraqi authority figures in Kuwait. The Iraqi education ministry in Kuwait fired 3,000 Palestinians in September 1990, and the dismissals of Palestinians from other sectors continued throughout October. The Iraqis also put pressure on the PLO office in Kuwait, which had refused to organize any Palestinian demonstrations and rallies in support of Iraq. The only Palestinian demonstration in Kuwait during the Iraqi occupation was actually a pro-Kuwait demonstration, with the Palestinian inhabitants of the Hawalli district waving photos of the Emir.
