Yami, who played an intelligence officer in the film, tweeted: "Gratitude forever to our Indian army, our audience who embraced It & gave it so much love! And entire Team of URI for being so fantastic & hard-working ! #1YearOfURI"
Kirti, who played flight lieutenant Seerat Kaur in the film, said: " It was an impactful and powerful role and people have given it so much love that it fills my heart with gratitude every time. Being a defense kid, I think the fact that I got to represent a uniform on screen, in a film like 'URI...', is something that will always stay very close to my heart."
She added that the "josh" is still super high and she hopes it remains the same.
"It's a tribute to all the Jawans in uniform who safeguard all the citizens of this country and protects us from all the harm," she added.
