The Syrian conflict is 13 years old. It's ridiculous to expect every article to give you the whole context every time, especially since anything anyone will write about said context will be extremely biased. This conflict had massive misinformation campaigns from all sides.

Evaluate the information for what it is, not for whether it gives you a lecture on the history of the conflict.

SANA is primarily a TV channel, and the articles are usually a summary / transcript of the TV reports. They show videos routinely of the trucks that are very clearly carrying oil through Al-ya'rabiya, which is a border crossing from Syria to Iraq that the US controls.
