There are three noteworthy prophecies of Ezekiel regarding Tyre that were fulfilled much after the book of Ezekiel was written and completed. The first one is regarding the demise of Tyre,
וּנְתַתִּיךְ לִצְחִיחַ סֶלַע מִשְׁטַח חֲרָמִים תִּהְיֶה לֹא תִבָּנֶה
עוֹד כִּי אֲנִי יְדֹוָד דִּבַּרְתִּי נְאֻם אֲדֹנָי
This verse contains two predictions: 1) that Tyre will be destroyed and never regain its previous stature. 2) that the island will become a spot for the fisherman to spread their nets (משטח חרמים). The first one indeed occurred in the times of Alexander the great. For six months he besieged it till he broke through their defenses and reduced it to ruins, and since then it was never rebuilt. The second one has also undoubtedly been fulfilled,
Historian Philip Myers said, “Alexander the Great reduced it [Tyre] to
ruins (332 B.C.). She recovered in a measure from this blow, but never
regained the place she had previously held in the world. The larger
part of the site … is now as bare as the top of a rock–a place where
the fishermen that still frequent the spot spread their nets to dry”
(General History for Colleges and High Schools [Boston: Ginn and Co.,
1889], p. 55). That fulfills the prophecies of Ezekiel 26:4-5, 14. The
island city was repopulated, later to be destroyed by the Moslems in
A.D. 1281. However, God said the mainland city would never be
rebuilt–and it never has. Jerusalem has been rebuilt many times but
Tyre will never be rebuilt because a prophet in Babylon said
twenty-five centuries ago, “Thou shalt be built no more” (Ezek.
There is one more remarkable prophecy regarding Tyre that its accuracy astounds the reader,
כִּי כֹה אָמַר אֲדֹנָי יֱדֹוִד בְּתִתִּי אֹתָךְ עִיר
נֶחֱרֶבֶת כֶּעָרִים אֲשֶׁר לֹא נוֹשָׁבוּ בְּהַעֲלוֹת עָלַיִךְ אֶת
תְּהוֹם וְכִסּוּךְ הַמַּיִם הָרַבִּים: (כ) וְהוֹרַדְתִּיךְ אֶת
יוֹרְדֵי בוֹר אֶל עַם עוֹלָם וְהוֹשַׁבְתִּיךְ בְּאֶרֶץ תַּחְתִּיּוֹת
כָּחֳרָבוֹת מֵעוֹלָם אֶת יוֹרְדֵי בוֹר לְמַעַן לֹא תֵשֵׁבִי וְנָתַתִּי
צְבִי בְּאֶרֶץ חַיִּים:
Indeed this has been fulfilled,
In his memoirs, a section is included concerning the city of Tyre.
From Sidon it is half a day’s journey to Sarepta (Sarfend), which
belongs to Sidon. Thence it is a half-day to New Tyre (Sur), which is
a very fine city, with a harbour in its midst.... There is no harbour
like this in the whole world. Tyre is a beautiful city.... In the
vicinity is found sugar of a high class, for men plant it here, and
people come from all lands to buy it. A man can ascend the walls of
New Tyre and see ancient Tyre, which the sea has now covered, lying at
a stone’s throw from the new city. And should one care to go forth by
boat, one can see the castles, market-places, streets, and palaces in
the bed of the sea (1907, emp. added.).
From this twelfth-century A.D. text, then, we learn that by that
period of time the city known as ancient Tyre lay completely buried
beneath the sea and a new city, most likely on some part of the
island, had been erected.
In addition, Benjamin Tudela’s quote corresponds precisely to the
statement that the prophet made in the latter part of chapter 26: “For
thus says the Lord God: ‘When I make you a desolate city, like the
cities that are not inhabited, when I bring the deep upon you, and
great waters cover you’” (26:19, emp. added).
These prophecies have been so amazingly accurately fulfilled, that it caused some scholars to doubt the date of its composition (the book of Ezekiel). But in reality it couldn't have been composed or even edited later than the second century BC (the time most of the Septuagint was written), and since the destruction of Tyre happened in the year 332 BC, there is not much room left for parts to have been inserted by editors. There is more evidence that the book has not been tampered with (since the prophecies of Ezekiel were written down during the exile), since the seemingly unfulfilled parts (the part with Nebuchadnezzar destroying Tyre, see below) were not excised from the book. In any case, the other two prophecies were surely not fulfilled until much later after the books of the Tanakh were canonized and reviewed by multitudes of people.

Regarding the unfulfilled prophecy of Nebuchadnezzar destroying Tyre, see previous link where he tries to resolve the issue, however in my opinion the issue still remains unresolved.
