As we have mentioned on this website before, Palestinians have a recognized maritime space in the Mediterranean Sea off the coast of the Gaza Strip.
In a map attached to the Oslo Accords in 1994 and 1995, Gaza’s maritime space is recognized by an agreement with Israel, which was witnessed (is this a guarantee?) by the United States, Russia, and Egypt.
Gaza’s maritime space extends 20 miles off Gaza’s coastline, straight out into the Mediterranean Sea.
This is where Israel has imposed a formal declared naval blockade.
