The United States pressed Turkey on Saturday to halt military strikes on Kurdish and Syrian regime targets Saturday in the northern province of Aleppo, as Ankara weighs a joint ground assault with Saudi troops.
"We are concerned about the situation north of Aleppo and are working to de-escalate tensions on all sides," State Department spokesman John Kirby said in a statement.
State-run news agency Anatolia, quoting a military source, said the armed forces shelled Syrian Kurdish Democratic Union Party targets around the town of Azaz, and also responded to regime fire on a Turkish military guard post in Turkey's southern Hatay region.
There were no further details on the nature of the Turkish strikes, but they likely would involve artillery fire from tanks.
