Jordan warned Israel on Sunday their peace treaty would be threatened by continued Jewish settlement building on occupied land sought by the Palestinians and any change to the religious status of a key Muslim shrine in Jerusalem.
"All such acts are incompatible with international law and international humanitarian law and if allowed to continue will ultimately imperil the treaty," Jordan's ambassador to Israel, Walid Obeidat, said at an event for the treaty's 20th anniversary.
Obeidat was referring to efforts by far-right Israelis to change the status of a plaza near the al-Aqsa mosque holy to Jews as the place where two ancient temples stood, and reports of plans to build more settlements in land Palestinians want for a state.
Prime Minister Benjamin Netanyahu has said Israel would not change the status of the holy site, which since Israel's capture of East Jerusalem in a 1967 war has been administered by Muslim authorities, and Jewish prayer held at the nearby Western Wall remnant of an ancient temple.
