Rescue workers have recently stated that up to 43 people were killed when a car bomb went off in a busy market in a rebel-held town in Syria along the Turkish border. 

The Syrian Civil Defence - a team of first responders - said the initial casualty count shows that at least 15 people died on Saturday in the explosion in Azaz, which is a border town roughly 20 miles north-northwest of Aleppo. 

The Syrian Observatory for Human Rights monitoring group has put the death toll at 19, and other activists said the number is likely higher after the explosion ripped through the packed market.

Many rebels and civilians who were pushed out of Aleppo city during a massive government offensive late last year and resettled in Azaz.

As of yet there has been immediate claim of responsibility.
