Car bombing kills 4 in Syria's Aleppo

At least four civilians were killed and many others wounded on Saturday when a booby-trapped car ripped through a marketplace in a rebel-held town in Syria's northern province of Aleppo, activists said.
The car tore through a vegetable marketplace in the town of Azaz, in the northern countryside of Aleppo on the borders with Turkey, the UK-based Syrian Observatory for Human Rights said, adding that women and children were among those killed.
It said the death toll is likely to rise due to the number of critically wounded people.
While the Observatory stopped short of giving further details, it is largely believed that the blast was part of the infighting among rival militant groups in Aleppo where an array of rebellious groups are plagued by a conflict of purposes and strategic gains.
A day earlier, a total of 15 people were killed as a result of the rebels' rocket shelling against government-controlled areas in Aleppo, where the western part of the city is still under the government control while the eastern one has fallen to the rebels long ago.
Syria has been gripped by deadly conflict since March 2011. Over 160,000 people have reportedly been killed and millions displaced due to the violence.
