The US military entered Syrian territory through a checkpoint on the border with Iraq and deployed in the oil fields in the northeast of the country, reports Al Ekhbariya TV channel.
The convoy included 22 army vehicles and two trucks moving under air cover.
About 90 percent of Syrian oil production is concentrated on the Eastern Bank of the Euphrates River. In October, US President Donald Trump announced the withdrawal of US troops from Northern Syria , but shortly after that said that part of the military will remain in the country.
According to Trump, the US goal is to "protect oil" from Islamic State terrorists since oil production in the area used to be their primary source of income. The US President noted that "maybe the time has come for the Kurds to move into this oil region" because "they need money."
