In 1976, the Israeli Defense Force (IDF) raided Entebbe Airport in Uganda and the Osiraq nuclear reactor in Iraq. This made officials in San'a aware that Israel would use force to keep its gateway to the Indian Ocean open. San'a's fears increased particularly since the Israeli Intelligence Services had frequently sent vessels to monitor any activity in the Red Sea. In addition, Israeli agents operated in the area to guarantee the safe passage of Israeli ships on their way to and from Eilat. San'a repeatedly called for an end to the Iran-Iraq war. In 1982 San'a not only condemned Israel for its invasion of Lebanon and the U.S. for facilitating that invasion, but also joined a ministerial delegation sent by South Yemen to all Arab capitals to discuss the issue. In addition, it joined South Yemen in informing PLO leader Yasser Arafat of its willingness to absorb Palestinian refugees.
