Antonio Riva (Chinese: 李安東; pinyin: Lǐ Āndōng; 8 April 1896 – 17 August 1951) was an Italian pilot and a World War I flying ace, credited with seven confirmed and seven unconfirmed aerial victories.

In 1951, he was executed by firing squad under the newly established People's Republic of China for allegedly conspiring to assassinate Mao Zedong and other Communist leaders.

[2] Riva began his successes while flying a Nieuport 11 with this fighter squadron when he shared a victory with Antonio Amantea and another Italian pilot.

[3] Riva was assigned on 10 September 1918 as commanding officer to form a new squadron, 90a Squadriglia, equipped with a new fighter aircraft, the SVA 5.

[2] Antonio was executed in Beijing, People's Republic of China, by a firing squad in 1951, along with a Japanese citizen, Ruichi Yamaguchi.

[5] The plot allegedly involved attacking Mao and other officials atop Tiananmen Gate with a mortar on 1 October 1950, during National Day celebrations.

Tarcisio Martina, the priest whose house was next to the other parts of the mortar, was sentenced to life imprisonment, although he was released and deported three years later.

It was alleged that the ringleader of the plot was an American serviceman named David D. Barrett, but he was simply a neighbor to the two who had moved out a year before.

Two decades later, PRC prime minister Zhou Enlai apologized to Barrett and invited him back to China.
