According to activists, six people have died in a gas attack by the Syrian government in the northwestern village of Sarmin, reports AFP.
All victims, including three children, were from the same family.
"Three children, their mother and father, and their grandmother suffocated to death after regime barrel bomb attacks," the Syrian Observatory for Human Rights told AFP.
Upon examining the dead after the attack, doctors from Sarmin told the Syrian Observatory for Human Rights that the cause of death was gas poisoning, which may have been emitted from the bombs.
Photos have also surfaced of the three youngest victims, showing their pale faces with dark circles around their eyes.
This is not the first time chemical weapons have been used in Syria. On August 24, 2013, a sarin gas attack killed hundreds of people in a Damascus suburb. It remains unclear who was responsible for the attack.
Kurdish forces also recently accused Daesh of using chlorine gas in roadside attacks in Iraq on three seperate occasions.
