A second bomb has struck Damascus just hours after a reported suicide attack at the Justice Palace in al-Hamidiyeh, Damascus, which killed at least 31 people.

Sana reports the attacker was being chased by security agents when he ran into the restaurant and detonated a suicide vest.

Hours before, a suicide bomber detonated an explosive device inside the main building of the Justice Palace, according to reports.

Government authorities ordered an evacuation of the area surrounding the Justice Palace over fears of further attacks, Almasdar News reports. The Justice Palace is located close to the famous Hamidiyeh market in Damascus.

"We were terrified because the sound of the explosion was enormous," an unidentified lawyer, who was in the building during the attack, told AFP. "We took refuge in the library which is on a higher floor. It was a bloody scene."
