(The place is probably Asyut, Wikipedia https://en.wikipedia.org/wiki/Asyut), less often written as Assiut).

The video and audio are poor quality, maybe filmed from the screen of another device- there's maybe a hint of fingers at the right side of the screen at approx. 16:40.

From approx. 17: 44, there's a BBC news report from Caroline Hawley, a BBC correspondent who covered Egypt, Libya and Sudan from 1999 (BBC profile http://news.bbc.co.uk/aboutbbcnews/hi/profiles/newsid_3787000/3787599.stm); the original must have been in much better quality.

The story is in the context of claimed Marian apparitions (Wikipedia https://en.wikipedia.org/wiki/Marian_apparition) but we don't see any Marian apparitions, so we are left with various lights and brief illuminations of the church. The latter might be due to entirely mundane sources, e.g. spotlights being flashed on and off, perhaps powerful photography flashes.

The perhaps out-of-focus "globular" light from approx. 1:29 could be almost anything. We don't see any part of the Church (or anything else) in this sequence.
The light very near the cross from about 2:47 might be the Moon; I'd guess there are others here who would be able to establish if this might be a possibility (if the camera time and date are correct).

If accurate, the dates at the lower left of the screen are from 21 August 2000 to 10 September 2000; plenty of time to arrange for good quality filming from a number of different viewpoints. But this doesn't appear to have happened.

If this (low quality) footage has been filmed from the screen of another device, the opportunities for hoaxing might be greater- manipulation of imagery on the first device might be harder to detect; the editing might allow inclusion of non-authentic footage though my feeling is perhaps this didn't happen- but nevertheless all lights seen probably have prosaic explanations.

The burden of proof is on claimants to demonstrate that these lights are probably not of mundane origin.
