More than 300,000 Syrian refugees flowed into Turkey to escape the ISIL advance into the Kobanî Canton. However, security forces did not allow People's Protection Units (YPG) militants and other volunteers to go the other way, using teargas and water cannons. On 30 September, errant shells landed on Turkish soil and the Turks shot back into Syrian territory, with Turkish armor being brought to the border to deter further incursions. Five civilians in Turkey were injured when a mortar hit their house. Turkey evacuated two villages as a precautionary measure. While dispersing Kurdish crowds, Turkish police fired teargas directly into a BBC news crew van, breaking through the rear window and starting a small fire.
