DAMASCUS - Two people were killed and 30 others injured when a car bomb exploded Sunday in Syria's northern city of Aleppo, as the country was mourning victims of the triple blasts the day before, state-run SANA news agency reported.

An "armed terrorist group" detonated a booby-trapped car in Aleppo's residential neighborhood of al-Sulaymanyia as the specialized authorities found the car suspicious and were trying to pull it out from the area, SANA said, adding that the car was parked near a Latin church and two schools.

Some witnesses told Xinhua that the spot of explosion was also near the Political Security Directorate in the area.

The explosion killed a law-enforcement agent and a woman, and wounded 30 civilians and security agents, two of them in grave conditions, said SANA, adding that the explosion destroyed the facade of a residential building and caused big material damage to nearby buildings.

Sunday's blast is not the first in Aleppo, Syria's second largest city. On February 10, two suicide bombers blew themselves up near two security compounds in Aleppo, killing at least 25 people.

The blast also came just a day after two suicide car bombers detonated their explosives near the aviation intelligence directorate and the criminal security department in the capital Damascus, killing 29 civilians and security personnel and wounding 140 others.
