Turkey has scrambled six F-16 fighter jets near its border with Syria after Syrian helicopters came close to the border, the country's army says.
Six jets were sent to the area in response to three such incidents on Saturday, the statement said, adding that there was no violation of Turkish airspace.
Last month, Syrian forces shot down a Turkish jet in the border area.
The incident further strained already tense relations between former allies.
Turkey's government has been outspoken in its condemnation of Syria's response to the 16-month anti-government uprising, which has seen more than 30,000 Syrian refugees enter Turkey.
Turkey's military has more than 500 miles of border with Syria to defend. It has now decided to treat everything that happens on the Syrian side of the border with extreme suspicion.
The scrambling of the jets is a sign of continuing tensions. A little over a week ago, Syria shot down a Turkish warplane. Syria says that the aircraft was flying inside Syrian airspace - a charge denied by Turkey.
Following this incident, the Turkish government announced that it had revised its military rules of engagement towards Syria. From now on, every military element that approached the Turkish border from Syria would be considered as a threat. The military has now acted on its new rules.
Turkey is keen to show that it's protecting its territory. The government allows its southern border region of Hatay to be used as a staging ground for Syrian opposition rebels. But it doesn't want this region to become an actual battleground.
On Friday, Turkey said it had begun deploying rocket launchers and anti-aircraft guns along the border in response to the downing of its F-4 Phantom jet on 22 June.
The move came after Prime Minister Recep Tayyip Erdogan warned that Turkey had changed its rules of military engagement and would now treat any Syrian military approaching the border as a threat.
Syria said the Turkish F-4 was shot down by air defence fire inside its airspace. Turkey insists it was downed by a missile after briefly entering and the leaving Syrian airspace.
