ALEPPO, Syria — The Russian-backed Syrian regime forces and their loyal militias regained full control of the strategic M5 highway, connecting Aleppo to Hama, Homs and Damascus. The Syrian government forces have been also rapidly advancing toward the towns of the western Aleppo countryside, which has come under heavy airstrikes since the beginning of February, and made new gains Feb. 16.

The Syrian regime and Russian warplanes and helicopters have caused horrific massacres against civilians, according to reports. Large groups of displaced Syrians from the targeted areas have been swelling near the Syrian-Turkish border.

The Turkish-backed opposition groups are trying to regroup and regain control over their areas. On Feb. 11, the opposition downed a Syrian regime helicopter, killing the pilot, and was able to retake the town of Sheikh Dames, in Maaret al-Numan some 20 miles (32 kilometers) south of Idlib city.

However, it appears that the Syrian opposition groups will not be able to stop the advance of the regime forces except through a ground attack with presumed support from Turkey. The balance of power has been greatly tipped in favor of the Syrian regime in the latest battles, given its sophisticated weapons and air support. The opposition, on the other hand, lacks capabilities, arms and ammunition.
