Istanbul's governor says that the New Year's nightclub attack that killed 39 people was executed on behalf of the Islamic State group.
Vasip Sahin told reporters that "It is clear that this was carried out in the name of Daesh." He was using an Arabic acronym for the militant group.
Sahin also confirmed the identity of the suspected gunman, who is now in custody and being questioned, saying he is an Uzbekistan national who had trained in Afghanistan.
