Arab media quotes Al Quds Al Arabi reporting that Israel, together with an unnamed Arab country, rescued some 400 Yemen Jews - which is probably all the Jews who were left - in a clandestine operation last month.
The special operation was carried out by Israeli commando forces who smuggled the Jews by helicopter.
The article says the Israeli Ministry of Absorption and Immigration confirmed the report, although I cannot find any Hebrew reports about this as of this writing. The newspaper quoted an Arab officer working in the Israeli army who participated in the operation ass saying that an Israeli commando unit carried out the operation in cooperation with an unnamed Arab country. The Jews were transferred by civilian aircraft to Ben Gurion airport. It isn't clear if this was a direct flight from the Arab country that helped out.
The report quoted an officer in the IDF saying that Yemeni Jews arrived at an agreed place outside their residential centers, and were in a difficult state of health, especially women and children.
The report quoted the spokesperson of the Ministry of Immigration and Absorption, "Alla Garteson," who said her ministry was happy with the result but could not give details.
