Turkish army tanks take up position on the Turkish-Syrian border near the southeastern town of Suruc in Sanliurfa province

Turkish army tanks take up position on the Turkish-Syrian border near the southeastern town of Suruc in Sanliurfa province October 6, 2014. Outgunned Kurdish fighters vowed on Monday not to abandon their increasingly desperate efforts to defend the Syrian border town of Kobani from Islamic State militants pressing in from three sides and pounding them with heavy artillery. Despite the heavy fighting, which has seen mortars rain down on residential areas in Kobani and stray fire hit Turkish territory, a Reuters reporter saw around 30 people cross over from Turkey, apparently to help with defence of the town.
