The belief in Egypt is that Ethiopia is being used by Israel and other powers to undermine the Arab world's most populous state and bring it down to its knees.
This position, analysts in Cairo said, is rooted in the Arab country's fear from getting caught in the middle of any future wars between Hamas and Israel.
The new warnings come less than a month after a retired Israeli diplomat, David Govrin, accused Egypt of violating the 1979 peace treaty with his country.
