We observed a saucer-shaped craft ascend from the horizon to the upper atmosphere in a fraction of a second, before separating

We observed one saucer-shaped object as you can see in the first photo. Then, it split (or the first object emitted a bunch of smaller objects) and the resulting objects took off in separate directions— straight up and straight down — (“reformed” post-split saucer up, small Vs / geometric line objects down - see second photo - zoom in to see detail - 4th photo is a zoom of one of these smaller objects), before the saucer shot due East across the Southern night sky, with incredible speed, while the smaller objects quickly disappeared. The saucer was chased immediately afterwards by what appeared to be a military drone, low and moving at high speed.
