Syrian opposition seeks rebel unity to rebuild army

The Syrian opposition wants the three main rebel factions in northern Syria to reunite as one army.

President Bashar al-Assad’s forces are on the move, retaking more territory while the rebels are retreating. Six years after the start of the uprising in Syria, the rebels have a choice to rebuild a strong army or face defeat.
