Final answer:
Jerusalem is the Israeli city that became a part of a new Palestinian state.
Step-by-step explanation:
The Israeli city that became a part of a new Palestinian state is Jerusalem.
In 1947, the United Nations proposed a plan to partition Palestine into separate Jewish and Arab states, with Jerusalem being an international city under UN administration. However, during the First Arab-Israeli War in 1948, Jordan occupied the eastern part of Jerusalem, including the Old City, while Israel controlled the western part.
After the Six-Day War in 1967, Israel gained full control of Jerusalem, and it has been a highly contested city ever since, with both Israelis and Palestinians claiming it as their capital.
