Syrian activists say a car-bomb explosion in the Syrian city of Aleppo has at least three people and wounded 25.
The Syrian Observatory for Human Rights said the attack was near a security building in the Suleimaniyeh neighborhood.
State media also reported a car bomb attack, saying it exploded between two residential buildings.
The blast came one day after officials said two vehicles packed with explosives on March 17 blew up near security buildings in Damascus, killing 27 people.
Both Damascus and Aleppo are seen as cities with high levels of support for President Bashar al-Assad.
United Nations estimates a year-long uprising against Assad has left more than 8,000 people dead.
