Iran's Supreme Leader Ali Khamenei said on Wednesday that Israel will disappear from the "landscape of geography," adding that its land will be returned to the Palestinians.

The comment was the last of a string of remarks made by both Israeli and Iranian officials amid continued debate over the possibility of a military resolution to the ongoing nuclear standoff between Iran and the West.

Referring to growing discussion over nuclear crisis earlier this week, Israeli Ambassador to the U.S. Michael Oren stressed in an interview to MSNBC that the Israeli clock "is ticking faster."

Oren said Israel appreciated U.S. Secretary of Defense Leon Panetta's reiteration that the U.S. is determined to prevent Iran from acquiring a nuclear weapon, but mentioned the "structural differences between the United States and Israel which we can't ignore."

On Tuesday, Iranian Defense Minister Gen. Ahmad Vahidi dismissed Israeli threats against his country as psychological warfare.

The semi-official Mehr news agency on Tuesday quoted Gen. Ahmad Vahidi as saying Israeli leaders are resorting to "psychological war" against Iran.

However, the war of words continued on Wednesday, with Mehr quoting Iran's Supreme Leader, in an apparent reference to the Israeli-Palestinian conflict.

According to Mehr, Khamenei said that the "light of hope will shine on the Palestinian issue, and this Islamic land will certainly be returned to the Palestinian nation, and the superfluous and fake Zionist [regime] will disappear from the landscape of geography."

The remark was reportedly made during a meeting with Iranian veterans of the Iran-Iraq war.
