ISTANBUL, TURKEY - DECEMBER 12: Turkish President Recep Tayyip Erdogan visits the blast site outside the Besiktas FC's Vodafone Arena Stadium on December 12, 2016 in Istanbul, Turkey. At least 44 people were killed and 160 other wounded in twin explosions outside Vodafone Arena Stadium and in nearby Macka Park a few hours after the night's soccer match on 10 December. The bombs apparently targeted police officers who were securing the match. The Kurdish nationalist group Kurdistan Freedom Hawks (TAK), which seeks an independent Kurdish state in eastern and southeastern Turkey, claimed responsibility for the attack, according to published reports.
