For three years rebels have fought against the regime of Syrian President Bashar al-Assad and, as the number of casualties continue to rise, the fighting continues to spill over into neighboring countries. While sometimes fighters from either side venture across borders or political leanings influence other country's stability, rarely does Syria's air force make incursions into foreign airspace. But, when it does happen, it does not end well.

After tracking two Syrian warplanes near their border, Turkish fighter planes shot down one of the Syrian planes. According to Reuters, Turkish general staff tracked the two Syrian MiG-23's near its border and warned them four times. The planes did not heed their warnings and, in response, Turkey deployed F-16s, one of which shot down a Syrian MiG. The pilot ejected.

In a campaign rally, Prime Minister Recep Tayyip ErdoÄŸan praised his country's military action. "A Syrian plane violated our airspace," said ErdoÄŸan, according to Reuters. "Our F-16s took off and hit this plane. Why? Because if you violate my airspace, our slap after this will be hard."

The Syrian government decried Turkey's actions, calling them "a flagrant act of aggression that is evidence of Erdogan's support of terrorist groups," according to the AFP. The reference is to the terrorist-affiliated rebel groups fighting in the provinces bordering Turkey. Though Syrian government forces have gained grown near the capital and the central provinces, their control wavers in the northern and eastern provinces.

According to Syrian sources, the planes were hunting down terrorists inside Syrian territory near Kasab. Rebel groups backed by terrorist organizations, including Al-Qaeda's Syrian affiliate Al-Nusra, launched a campaign on Tuesday to take over the area, reports AFP.

While the violence spills over into Syria's northern neighbor, Lebanon also has experienced some Syrian related violence. However, no Syrian plane or soldiers crossed their border, instead fighting broke out between supporters of the rebels and supporters of al-Assad, according to the BBC.
