Amid claims that the Turkish government funds IS fighters, several Kurdish demonstrations broke out near the Turkish-Syrian border in protest against the government's inactivity.[284] These protests escalated during the fighting in the border town of Kobane, with 42 protestors being killed following a brutal police crackdown.[285][286] Voicing concerns that aid to Kurdish fighters would assist PKK rebels in resuming terrorist attacks against Turkey, Erdoğan held bilateral talks with Barack Obama regarding IS during the 5–6 September 2014 NATO summit in Newport, Wales.[287][288] In early October, United States Vice President Joe Biden accused Turkey of funding IS, to which Erdoğan angrily responded, "Biden has to apologize for his statements" adding that if no apology is made, Biden would become "history to me." Biden subsequently apologised.[289] In response to the U.S. request to use İncirlik Air Base to conduct air strikes against IS, Erdoğan demanded that Bashar al-Assad be removed from power first.[290] Turkey lost its bid for a Security Council seat in the United Nations during the 2014 election;[291] the unexpected result[292] is believed to have been a reaction to Erdoğan's hostile treatment of ethnic Kurds fighting ISIS on the Syrian border[293][294] and a rebuke of his willingness to support IS-aligned insurgents opposed to Syrian president Bashar al-Assad.[293][294]
