A big explosion in the city of Aleppo in Syria reportedly killed five people on Saturday.
The BBC reports it went off in a car wash in the Tall al-Zarazeer district. The business was reportedly linked to pro-government militias.
There were also two blasts in Damascus, but no-one was hurt.
One of the bombs was planted under a car in a busy thoroughfare. It damaged nine vehicles and left a crater in the street.
The BBC says bombs are now a regular occurrence in Damascus and Aleppo, which have otherwise been spared the worst of the conflict.
