"We are here because the civilians requested that we come and liberate the country from terrorists and armed gangs."
Damascus and Syria's second biggest city, Aleppo, have come under heavy fighting as President Bashar al-Assad steps up efforts to crush rebel forces.
A bomb attack that killed four of Assad's closest lieutenants last week prompted his enemies to say that Assad's time in power is drawing to a close.
But in the days that have followed, Assad's forces have noticeably toughened their response.
