DT took to Twitter Saturday with a message to the folks protesting in Tehran right now, decrying their government recently shooting down a Ukraine International Airlines plane by mistake ... and killing over 150 passengers, many of whom were Canadian citizens.

The Prez wrote, "به مردم شجاع و رنج کشیده ایران: من از ابتدای دوره ریاست جمهوریم با شما ایستاده‌ام و دولت من همچنان با شما خواهد ایستاد. ما اعتراضات شما را از نزدیک دنبال می کنیم. شجاعت شما الهام بخش است."

We know what you might be thinking if you're a native English speaker ... THE HELL DOES THAT MEAN?!? Not to worry, 'cause 45 sent out an accompanying translation. En ingles, it means ... "To the brave, long-suffering people of Iran: I've stood with you since the beginning of my Presidency, and my Administration will continue to stand with you." He adds, "We are following your protests closely, and are inspired by your courage."

He wasn't done with the Farsi ... Trump followed up by tweeting the above message, which translates, "The government of Iran must allow human rights groups to monitor and report facts from the ground on the ongoing protests by the Iranian people. There can not be another massacre of peaceful protesters, nor an internet shutdown. The world is watching."

Don't worry ... we Google Translated it ourselves, and it looks like Donnie got it right here.

If you haven't seen the protests on the ground in Tehran yet, they're pretty crazy -- with thousands taking to the streets and demanding the Supreme Leader Ayatollah Ali Khamenei resign after Iranian officials admitted they shot the Flight 752 in error ... mistaking it for a threat, this amid rising tensions between the U.S. and Iran after Soleimani's death.

Some folks were even reportedly chanting "Death to liars" during the demonstrations, in their own language of course.
