According to SANA news agency, the ministry called for immediate action against Turkey, Saudi Arabia, and Qatar, who it claims support and finance terrorism in the country.
The blast occurred after a bomber blew up his explosives at the entrance of the holy shrine of Hazrat Zaynab (Peace be upon her) in the capital’s suburbs.
It was followed by a second blast when an explosive-laden car parked on the nearby al-Tin street went off shortly afterwards.
The ministry noted that such attacks are aimed at boosting the morale among the terrorists, who have suffered dramatic collapse in their ranks following a recent surge of military gains by the Syrian forces and their allies.
The letters noted that Syria will continue with its push against terrorism and efforts to protect the nation against the Takfiri threat.
