They also underscore the difficulties foreign powers face trying to unify Syria's opposition, while trying to hasten the downfall of Syrian president Bashar al-Assad.

On Friday, the Turkish government once again denounced the Syrian regime, claiming it had no legitimacy.

Turkish Foreign Minister Ahmet Davutoglu then announced his government would be recognizing a newly formed Western-backed opposition movement known as the National Coalition Forces of the Syrian Revolution as "the legitimate representative of the Syrian people."

But Turkey has failed to deter the Syrian military from carrying out operations within sight of the Turkish border.

On Friday, Syrian and Turkish witnesses told CNN they saw Syrian government aircraft bombing targets near the Bab el Hawa border get between the two countries.
