Reuters found the same video footage published by two YouTube channels on February 3, 2020 and February 28, 2020. (see here and here)
The video material published on February 3 on Youtube contains a description in Russian. In the Albanian translation it means "Syria. War in Syria. Surface-to-surface missiles destroy Turkish al-Qaeda militias west of Aleppo."

Analyze:
The website "The Reis" has published a 2020 video claiming that the footage depicts the October 2023 conflict between Israel and Hamas, captioning it "Hamas continues to strike Israel."
This video material published by the website "The Reis" is rated as "Unverified Content".
Reasoning:
The “Unverified” rating is given to those media reports that do not provide sufficient information to confirm the claims made in the report, and which have not been able to confirm the same due to the lack or non-possession of reliable sources.
