Turkey said it had downed a Syrian military helicopter today, accusing the neighbouring nation of violating its airspace in the tense border region, amid a new international diplomatic push to end Syria's civil war.
The Syrian MI-17 helicopter was detected two kilometres (1.2 miles) inside Turkish airspace and shot down five minutes later after failing to heed warnings, Deputy Prime Minister Bulent Arinc told reporters.
"It was continuously warned by our air defence but as the violation continued, it fell on Syrian soil at 2:25 pm (1125 GMT), having been hit by missiles from our planes," which took off from their base in the eastern province of Malatya, he added.
Arinc said there was no information about the fate of its crew because the helicopter fell on Syrian soil.
The downing of the helicopter comes at a time of heightened diplomatic activity to resolve the Syrian crisis, which has spillover effects across the region.
Turkey has changed its military rules of engagement in response to repeated gunfire from the Syrian side towards the border areas, Arinc added.
In a statement posted on its website, the Turkish military said the Syrian helicopter was detected when it was 26 nautical miles away from its airspace and was warned until it was five nautical miles away.
"Despite that, the Syrian helicopter kept on approaching the Turkish airspace," the army said, adding that it violated the airspace in the vicinity of the Guvecci border post, while it was flying at an approximate altitude of 14,200 feet.
One of the two patrolling Turkish F-16 jets shot down the helicopter which fell almost one kilometre inside Syrian territory, according to the army.
The incident occurred as the UN Security Council is expected to start negotiations this week on a resolution to back a plan agreed at the weekend by Russia's Foreign Minister Sergei Lavrov and US Secretary of State John Kerry to destroy Syria's chemical stockpile.
A cautious Turkey welcomed the US-Russian accord but warned that Damascus could be seeking to buy more time for its deadly military campaign.
The Turkish-Syrian border, which is more than 500 miles (805 kilometres) long, has become increasingly tense. More than 500,000 refugees have fled the fighting in Syria. Half of them took up residence in camps while the remainder were spread throughout the country.
The Turkish military has repeatedly struck back in response to shelling and mortar rounds that landed on its territory since a deadly shelling hit a Turkish border region last October, killing five people.
Relations have deteriorated between Damascus and Ankara, who were once close allies, since the outbreak of an uprising against Syrian President Bashar al-Assad and the unleashing by the regime of a brutal crackdown against dissent in March 2011.
