On June 26, 1978 the collective leadership of South Yemen's ruling party, led by Abdul Fattah Ismail, overthrew and executed President Salim Rubai Ali after a brief violent power struggle in Aden, ending the rule of the head of state who had led the country since 1969 and clearing the way for a hardline Soviet-aligned regime. Rubai Ali, a Maoist-leaning figure, had chaired the Presidential Council of the People's Democratic Republic of Yemen and had been moving toward rapprochement with North Yemen and a more China-oriented line, putting him at odds with the Soviet-oriented faction around Abdul Fattah Ismail. The crisis came to a head after the North Yemeni president Ahmad al-Ghashmi was killed on June 24, 1978 by a bomb carried by a South Yemeni envoy, an act widely attributed to Aden but disputed.
Two days later, on June 26, a pro-Soviet people's militia loyal to Ismail defeated troops loyal to Rubai Ali, who was arrested and executed the same day, accused of responsibility for al-Ghashmi's death.

Salim Rubaya Ali served as the second head of state of South Yemen from 22 June 1969 until his execution on 26 June 1978, when the collective leadership of the Yemeni Socialist Party led by Abdul Fattah Ismail overthrew and executed him.
A US State Department historical note records that fighting broke out in Aden days after al-Ghashmi's murder in Sana, and that the New York Times reported that on June 26 a pro-Soviet people's militia led by Abd al-Fattah Ismail defeated troops loyal to Salim Rubayi Ali, who was arrested and executed.

Editorial Note
Killings protocol applied: the deposed head of state Salim Rubai Ali was executed, and every death claim is cited and attributed, including a primary US State Department historical note referencing contemporary New York Times reporting. Coding note: the dataset labels this a palace coup with a killed fate, accurately, as it was an internal party power struggle in which the sitting chairman was defeated militarily, arrested, and executed the same day. Context and contestation: the immediate trigger, the June 24 killing of North Yemeni president al-Ghashmi by a bomb attributed to a South Yemeni envoy, is widely blamed on Aden but remains disputed; sources differ on whether Rubai Ali or the Ismail faction was responsible, and this is recorded as contested rather than resolved. Ties: this connects to the South Yemen thread from the 1969 Corrective Move that first brought Rubai Ali's faction to dominance. Aftermath: Abdul Fattah Ismail became de facto leader and secured a 1979 friendship treaty with the USSR; he himself vanished in the 1986 South Yemen civil war, later context.
