The man suspected of carrying out
the New Year's Eve attack on a nightclub in Istanbul was trained in
Afghanistan, the city's governor says.
| The suspect is an Uzbek national |
Thirty-nine people died in the attack on the Reina club with dozens wounded. Citizens of Israel, France, Tunisia, Lebanon, India, Belgium, Jordan and Saudi Arabia were among the victims.
So-called Islamic State (IS) said it was behind the attack, saying it was revenge for Turkish military involvement in Syria.
Police detained the man on Monday evening in a raid on an address in the Istanbul suburb of Esenyurt. Initial reports said a Kyrgyz man was also held but Mr Sahin said on Tuesday that a man of Iraqi origin and three women of Egyptian and African origin were detained.
A picture of Abdulkadir Masharipov taken shortly after his arrest showed him being held by the neck by an officer with his face bruised and bloodied.
