Michael arrived in the city just a day before the event, with the hope of achieving his murder plans. He thereafter, went to a local shooting range where he was said to have mastered how to use a gun for the first time.
If convicted, he faces up to 30 years in prison.
Meanwhile Donald Trump has responded to the airport attack in Istanbul by saying that the “terrorist threat has never been greater.”
“Our enemies are brutal and ruthless and will do anything to murder those who do not bend to their will. We must take steps now to protect America from terrorists, and do everything in our power to improve our security to keep America safe,” the Republican presidential candidate said.
In the same line, Hillary Clinton said the attack “reminds us that the US cannot retreat” in the face of threat and the US must deepen cooperation with allies in the Middle East and Europe.
