The facades of the U.S. missions in Seoul and Chennai, India, are partially hidden behind large rainbow flags, while the embassy in New Delhi is aglow in rainbow colored lights. The website for the embassy in Santiago, Chile, shows a video of the chief diplomat raising a rainbow flag last month for the International Day Against Homophobia, Transphobia and Biphobia.
Fag flags can be displayed. I believe the restriction is they can’t be flown on the main flag display pole. It is being reported differently by several outlets.
