The bomb detonated outside a police station in the predominantly Christian Bab Touma neighborhood, said the Associated Press.
Syrian state news SANA said Assad supported "any sincere effort to find a political solution to the crisis, based on respect for Syrian sovereignty and rejecting foreign intervention."
The president was quoted as saying a solution "must be centered around the principle of halting the terrorism and … commitment by the countries involved in supporting, arming and harboring the terrorists in Syria to stop these actions."
Brahimi arrived in Syria on Friday after visiting a number of Middle Eastern countries in a bid to unite international efforts behind a solution for the conflict in Syria, which is believed to have taken some 30,000 lives in over a year of violence.
Former envoy Kofi Annan resigned in frustration after trying to push through a peace plan to implement a cease-fire between Assad and an armed insurrection against his rule.
Brahimi has called on both sides to lay down arms in honor of the Muslim holiday of Eid al-Adha, or the Feast of Sacrifice, which began Friday.
The UK-based Syrian Observatory for Human Rights said 140 people were killed in violence in Syria on Saturday, reported Reuters.
After Brahimi met with Assad he repeated his call for a ceasefire.
"Everyone can start this (ceasefire) when they want, today or tomorrow for example, for the period of the Eid and beyond," Brahimi told reporters at a Damascus hotel.
