A prominent Syria analyst has told Al Jazeera that President Bashar al-Assad's forces have a "serious advantage" over opposition fighters, after the fall of Homs to the government.

Joshua Landis, director of the Centre for Middle East Studies at the University of Oklahoma, said the Syrian army and its allies have benefitted from centralised command and support from Iran and Russia.

After their "very important" gains in Homs, the Syrian armed forces would concentrate on retaking Aleppo, Landis said.
