The Karni Cargo Terminal is located 1.5 km west of Kibbutz Nahal Oz, on the borderline between Israel and the Palestinian Authority in the Gaza Strip. 

The Nahal Oz passageway is located north of the terminal.  Initially the terminal served as a central passageway for the entrance and departure of Palestinian workers to and from Israel. Erez is now used as the main passageway.

The name "Karni" took root over the years.  It is named after the deceased Joseph Karni, the founder of Kfar Yona. In response to then Defense Minister Moshe Dayan's call in 1967, immediately after the Six-Day War, Karni set up a modern packing warehouse used for sorting citrus fruit in the Sajayia neighborhood in Gaza, which is near the present-day cargo terminal.

The Ali Montar hill became known for the harsh battles that took place there between the Turks and the British in WW1 (1917).  In the most crucial battle of the war, General Allenby defeated the Turks, paving the way for the British to conquer Israel, thus bringing to an end the Turkish rule over the land.

Karni's packing warehouse was used for sorting citrus fruit coming from Gaza. The fruit was then marketed to the Persian Gulf countries and was then transferred through the Jordan bridges. The warehouse operated until 1987, its closure triggered by a tragic event.  On the eve of what is now known as the First Intifada, the warehouse manager and his deputy were murdered by Palestinian workers, who were members of the permanent staff on site.

The Palestinians call the passageway "Al-Montar", after the The Ali Montar hill.
