What is the film title of last two resistance fighters who hug each other at the same time as they have to shoot each other in the head after they are trapped in cellar in german occupied territory?

It's the 1976 movie Operation Daybreak.

Sorry, not correcting your 1976 date comment, just copied and pasted from IMDb, then realised it was different. I couldn't remember the name of this and was searching. Too slow to get the answer first.

Thank you so much
