According to Fares al-Vayoush, rebel commander of the Free Syrian Army, foreign countries have supplied Syrian revels with surface-to-surface Grad rockets in response to Russia's offensive in Aleppo.

Reuters news agency reported on Wednesday that rockets for the Grad BM-21 multilaunch systems with ranges of 22km and 40km have been given to the rebels in excellent quantities.

Al-Bayoush said that the rockets are to be used in clashes in Aleppo, Hama and the coastal region of Syria.

He further said that this type of weapons had not previously been given to the rebel forces.

However, he went on to say that the rebels are already using Grad rocket Stocks that they had previously captured from the Syrian army reserves.

The rebel commander told Reuters that "there has not yet been any sign of the rebels receiving anti-aircraft missiles they had requested from their foreign partners."

Reuters reported that the ammunitions have been given to the Free Syrian Army through a US-backed coordination center in Turkey.

Al-Bayoush added that the newly received missiles have been used against government positions near Aleppo before.

Russia and Iran have been supporting Syrian President Bashar Assad and his government in the conflict, while the United States and Western countries, as well as the Arab states in the region have sided with the so-called moderate rebels.
