Watch till the end, what could that be?

I live in Lebanon, Beirut and sightings like these are not common Bec we don’t even have technology for that stuff, the thing is this thing was followed by another one and they were following each other and i got a video of the 2nd one, I’ll post it soon but during the video it stopped mid way and was fast enough to be an airplane and would head back fast, could be a drone? Also it was glowing red and blue like flashes of red and sometimes switched to blue but it was unclear in the cam!
