It wasn't Iranian waters.
amazing how you're the only person that has that information.
the rest of us are going off of statements from both governments that say it was, but I'm sure you know better
Iranian "claimed" waters is different than what is recognized internationally. Those waters are claimed by Iran and 4 other Arab nations.
According to you. nobody else is saying that
Nobody really "owns" the Persian Gulf, it's a body of water bordering Iran and many Arab states, and the world's most used route for oil tankers. It's been disputed over the hundreds of years, including even it's name. Technically anything beyond 12 nautical miles from the shore of a country is considered international waters, and the straight of Hormuz is in the Persian Gulf, where the sailors were captured, is about 20 miles wide.

Territorial waters or a
territorial sea as defined by the 1982
United Nations Convention on the Law of the Sea,is a belt of
coastal waters extending at most 12
nautical miles (22.2
km; 13.8
mi) from the
baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships (both military and civilian) are allowed
innocent passage through it; this sovereignty also extends to the airspace over and seabed below. Adjustment of these boundaries is called, in international law,
maritime delimitation.
