[2][3] At the age of 16, he joined Kibbutz Ein Harod, and then the Nahal in 1953, where he completed officers and combat sergeants courses.

[2] Due to his Arabic skills, Cohen worked in Nablus and the surrounding refugee camps, trying to recruit Palestinians to spy for Israel.

[1] At Shin Bet, Cohen led the investigation that uncovered a Syrian-directed Jewish-Arab spy ring in Israel.

Cohen interrogated the spy ring's alleged leader in Israel, Daud Turki, a Palestinian-Israel anti-Zionist politician.

[2] On the morning of Tuesday, 23 January 1973, Cohen met one of his informants, a Palestinian medical student and Fatah activist living in Seville named Samir Mayed Ahmed,[6] at Café Morrison on Calle Jose Antonio, later renamed the Gran Vía.

After his body had been flown back to Israel for burial, Israeli authorities revealed his true name and government affiliation.

[4][7] Later that day, Black September Organization issued a public claim of responsibility for the assassination, alleging that Cohen, whom they incorrectly identified as Uri Molov, had been shadowing Arab intelligence officers.
