Furthermore, the success of the 1991 Persian Gulf War created new opportunities for Middle East peacemaking. In October 1991, under the sponsorship of the United States and the then Soviet Union, Middle East peace talks were held in Madrid, where Israel and a majority of its Arab neighbors conducted direct bilateral negotiations to seek a just, lasting, and comprehensive peace based on UN Security Council Resolutions 242 and 338 (and 425 on Lebanon) and the concept of "land for peace." Lebanon, Jordan, Syria, and representatives of the Palestinians continued negotiating until the Oslo interim peace accords were concluded between Israel and the Palestinians in September 1993 and Jordan and Israel signed an agreement in October 1994.
