Suspects in Swift concert terror plot wanted to 'kill as many people as possible'

The two suspects in the foiled terror plot on Taylor Swift concerts in Vienna appeared to be inspired by the Islamic State group and al-Qaida, Austrian authorities said Thursday and that they confessed to planning to “kill as many people as possible outside the concert venue.”

Three sold-out concerts were canceled Wednesday at Ernst Happel Stadium because of the plot, which was to be executed Thursday and Friday. 

Concert organizers expected up to 65,000 fans inside the stadium at each concert and as many as 30,000 onlookers outside, according to the Associated Press.

Officials said the19-year-old Austrian suspect began working on the plot in July and had uploaded an oath of allegiance to the leader of the Islamic State group militia. He planned to use knives or homemade explosives to carry out the attack outside the stadium, the wire service also reports.

They also found Islamic State group and al-Qaida material at the home of the second suspect, a 17-year-old Austrian. He was employed a few days ago by a company providing services at the venue for the concerts.
