The information comes from Syrian officials after a suspected terrorist cell was arrested during a series of raids in the capital and surrounding countryside.
Preliminary investigations into the members of the cell involved in the bombings in Damascus on July 7 have shown that the group had links to IS, said Ahmad Dalati, head of internal security in the Damascus region, on Syrian state television.
According to Syria's Interior Minister Anas Khattab, the identities of the perpetrators will be revealed once the investigations are complete.
One person was killed and dozens were injured in the explosions, which occurred during French President Emmanuel Macron's visit to Damascus.
