Arab League Secretary General Amr Moussa said Arab countries would never put up with Israel's occupation of their lands during that war, including East Jerusalem, the West Bank, the Gaza Strip, Egypt's Sinai Peninsula and Syria's Golan Heights.
Egypt was able to recover Sinai in 1982, but the other captured territories remain under Israel's control to this day.
Palestinian Authority President Mahmoud Abbas warned in his televised anniversary speech Tuesday that the Palestinian people were on the brink of a civil war, one which may prove even more disastrous that the four decades of Israeli occupation.
Abbas said ongoing infighting between the radical Islamist movement Hamas and his more moderate Fatah was his greatest concern now. The two forces forged a coalition government in March, but it has so far proved unable to efficiently run the Palestinian Authority, with supporters of the two rival camps routinely engaging in gun battles.
However, Abbas reiterated the Palestinian people's resolve to have the Israelis withdraw from occupied territories and to establish Palestine as a sovereign state.
But he criticized Palestinian militants for provoking Israeli military action by firing rockets at targets near Gaza. A recent rocket barrage prompted Israel to resume its incursions into the costal strip, of which it pulled out in 2005.
