Moroccan expeditionary forces fought alongside a coalition of Arab countries in the Yom Kippur War against Israel. In 1986, King Hassan II invited then Israeli Prime Minister Shimon Peres for talks, becoming the second Arab leader to host an Israeli leader after Anwar Sadat. Following the September 1993 signing of the Israeli-Palestinian Declaration of Principles, Morocco accelerated its economic ties and political contacts with Israel. In September 1994, Morocco and Israel announced the opening of bilateral liaison offices. When the king died in 1999, then-prime minister Ehud Barak and the Moroccan-born foreign minister David Levy flew to Rabat for his funeral. The foreign offices were closed in 2000 following sustained Israeli-Palestinian violence. In September 2016, Moroccan King Mohammed VI sent his personal adviser Andre Azulai, who is Jewish, to attend the state funeral of former Israeli Prime Minister and President Shimon Peres.
