Turkey's state-run news agency says a Syrian shell landed on Turkish territory for a sixth day, but made no mention of any immediate Turkish retaliation.
The Anadolu Agency said the shell landed on a cotton field in an area close to the border town of Altinozu, in Hatay province on Monday. People were working in the field at the time, but no one was injured.
Turkey and Syria have been firing artillery and mortars across their volatile border since Wednesday after shelling from Syria killed five civilians.
The exchange of fire stoked fears that Syria's civil war will escalate into a regional conflagration drawing in NATO member Turkey.
