Turkey’s foreign minister said on Wednesday that the gunman had been identified but provided no further details*2 . Turkish media had reported he was believed to be an ethnic Uighur from central Asia, possibly Kyrgyzstan.
Uighurs, a largely Muslim, Turkic-speaking minority in far western China with significant diaspora communities across central Asia and Turkey, were among those detained on Thursday in Selimpaşa, a coastal town just to the west of Istanbul. Turkish news agencies said investigators had received intelligence that individuals who may have helped the gunman were there.
It was not immediately clear how many people were detained on Thursday, but at least 36 people have been held since the attack, according to earlier media reports.
