Final answer:
Jaffa was secured by Israeli forces in late April to early May of 1948 during the Arab-Israeli War of 1948, also known as Israel's War of Independence. Jaffa was then under Israeli control by the time of the Six-Day War in 1967 when Israel solidified control over additional territories.
Step-by-step explanation:
The city of Jaffa, historically an important port city, changed hands multiple times over the centuries. The most renowned capture of Jaffa in modern history occurred during the Arab-Israeli War of 1948, also known as the War of Independence for Israel.
Following the expiration of the British mandate, Israel declared independence on May 14, 1948, and was promptly invaded by neighboring Arab states. The Israeli forces managed to secure Jaffa in late April to early May 1948, as part of a broader military campaign to establish control over their territory.
Subsequently, after the Six-Day War in 1967, Israel captured and solidified its control over additional territories, including East Jerusalem, the West Bank, the Golan Heights, the Sinai Peninsula, and the Gaza Strip. Although Jaffa is not explicitly mentioned in the context of the 1967 conflict, it was within the boundaries of Israel at that time and thus fell under its control.
