The People`s Protection Units (YPG), which is the military wing of the PYD, had previously threatened Turkey with terror attacks with a video released in February this year where the group declared war on Turkey.
Both the PYD and the YPG are the offshoot of the PKK terrorist organization operating in Syria.
Istanbul was rocked by twin blasts late Saturday, which killed 38 people and injured 155 others, 14 of whom are in critical condition. Officials have noted that initial findings suggest the brutal attack was carried out by the PKK terrorist organization.
