Dora Bloch[a] (née Feinberg; October 1902 – July 1976) was an Israeli hostage on Air France Flight 139 on 26 June 1976.

Taking off from Tel Aviv, Israel, and destined for Paris, France, the plane soon landed in Athens, Greece, for a scheduled stopover and was subsequently hijacked by two Palestinians from the Popular Front for the Liberation of Palestine and two Germans from the Revolutionary Cells, who rerouted to Benghazi, Libya, and then to Entebbe, Uganda, where they received support from Ugandan president Idi Amin.

Bloch, who had become ill during the flight, was taken to a hospital in Kampala and was therefore not among the 102 hostages who were rescued when Israel executed Operation Thunderbolt aka 'Operation Yonatan' on 4 July 1976.

She disappeared shortly after the hostages were rescued; her status as a British citizen and Amin's complicity in the hijacking resulted in the United Kingdom severing diplomatic ties with the Commonwealth country.

[6] On 27 June 1976, Bloch, aged 73, was on Air France Flight 139, an Airbus A300 plane, travelling to New York City for her youngest son Daniel's wedding.

[10][11] Bloch's son Ilan Hartuv, who was freed during the subsequent Operation Entebbe counter-terrorist hostage-rescue mission,[6] was able to speak to a Ugandan doctor about his mother's health.

[9] Henry Kyemba, then Uganda's Minister of Health, said that he had allowed Bloch to stay in hospital for an extra night before being returned to the other hostages.

[14] As a result, she was visited by James Hennessy, then-High Commissioner of the United Kingdom to Uganda,[10][14] and Peter Chandley, second secretary of the British High Commission in Kampala.

[5][14] The reason for this was that four men including Farouk Minawa, head of the State Research Bureau (Ugandan secret police) and Idi Amin's Chief of Protocol Nasur Ondoga had taken Bloch from her hospital bed and murdered her.

The United Kingdom suggested a resolution that condemned both the hijack and the loss of life, so as not to endanger the lives of Britons in Uganda, including Bloch.

[8][10] After the Uganda–Tanzania War,[17] Tanzanian troops discovered Bloch's body in 1979 in a sugar plantation around 30 kilometres (20 mi) from Kampala,[6][7] near the Jinja Road.
