"What France suffered from – savage terror – is what the Syrian people have been enduring for over five years,” he said on Saturday, hours after the attacks in France.
The attacks in France were carried out late on Friday, when assailants struck at least six different venues in and around the French capital.
Since March 2011, Syria has been beset by foreign-backed militancy, which has so far claimed the lives of over 250,000 people and displaced millions of others.
French President Francois Hollande has said the attacks were an "act of war” carried out by the Daesh Takfiri terrorist group.
The group has overrun about a third of Syria, where it is tyrannizing the civilian population.
France is among the Western countries that have been supporting the militants fighting against the Syrian government. As part of a US-led coalition, the country has also been conducting air raids against what it alleges to be Daesh positions in the violence-scarred Arab country.
Assad complained back in May that the so-called coalition against Daesh does not aim to "do away” with the terror group, adding, "They want to use this terrorist structure for threatening and blackmailing other countries.”
Also on Saturday, Daesh released an undated video, threatening to attack France as long as the aerial campaign continued.
"As long as you keep bombing you will not live in peace. You will even fear traveling to the market,” said a Daesh member in the footage.
