The US department of defence has raised its concerns with Turkey after a Turkish news agency published a map of US military bases in northern Syria.
The Turkey’s state-run Anadolu News Agency printed the map Wednesday, showing 10 U.S. locations in a portion of Syria under Syrian-Kurdish control, Voice of America reported Wednesday.
The Kurdish People's Protection Unit is the armed branch of the Kurdish Democratic Party, which Turkey considers to be a terrorist group. However, the US supports the groups as they help combat the Islamic State in Iraq and Syria (ISIS).
A Pentagon spokesman said US military officials cannot identify the source of the map, but "would be very concerned if officials from a NATO ally would purposefully endanger our forces by releasing sensitive information."
