At about 2 a.m. local time, Iraqi forces invade Kuwait, Iraq's tiny, oil-rich neighbor. Kuwait's defense forces were rapidly overwhelmed, and those that were not destroyed retreated to Saudi Arabia. The emir of Kuwait, his family, and other government leaders fled to Saudi Arabia, and within hours Kuwait City had been captured and the Iraqis had established a provincial government. By annexing Kuwait, Iraq gained control of 20 percent of the world's oil reserves and, for the first time, a substantial coastline on the Persian Gulf. The same day, the United Nations Security Council unanimously denounced the invasion and demanded Iraq's immediate withdrawal from Kuwait. On August 6, the Security Council imposed a worldwide ban on trade with Iraq.
