The mother of Syrian Kurdish People's Protection Units (YPG) militant Seydo Mehmud mourns above his grave on October 11, 2014 in the Turkish town of Suruc, Sanliurfa province, during the funeral of YPG militants fighting against Islamic State (IS) group jihadists for the control of the mainly-Kurdish Syrian town of Ain al-Arab, known as Kobane by the Kurds. Turkey has tightened security of its porous Syrian border after the escalating fighting in Ain al-Arab sparked the exodus of 200,000 refugees across the frontier.
