Hundreds of protesters in Iran refused to trample US and Israeli flags and denounced others who did as rallies continued against the regime for the downing of a Ukrainian passenger jet that killed all 176 people on board.

Videos and reports emerged Sunday showing the crowds deliberately walking around the edges of the massive flags painted on the pavement of a university in Tehran.

Those who did walk across the Stars and Stripes and the Star of David were immediately pointed at and booed, with the crowd chanting “shame on you.”

Many of the protesters shouted, “Our enemy is Iran, not America.”

Hillel Neuer, the executive director of the human rights group UN Watch, tweeted out a video of the crowds taking pains from treading on the flags on Sunday.

“These courageous Iranian students who refuse to trample the U.S. & Israeli flags represent the hope for a better Middle East. Engage with and promote them instead of their oppressors, and maybe Iran-backed wars & terror across the region will end,” he posted.

The unrest surged across Tehran and other Iranian cities and towns for a second day on Sunday after Iran’s Islamic Revolutionary Guard admitted mistakenly shooting down the Ukrainian airliner on Wednesday.

Trump on Sunday continued to show his support for the protesters as he did Saturday in a series of tweets.

“To the leaders of Iran – DO NOT KILL YOUR PROTESTERS. Thousands have already been killed or imprisoned by you, and the World is watching. More importantly, the USA is watching,” the president wrote on his Twitter page. “Turn your internet back on and let reporters roam free! Stop the killing of your great Iranian people!”

He also posted the tweet in Farsi.
