Taylor Swift is back with concerts in London after a terrorist threat in Austria

Megastar Taylor Swift will take to the stage in London on Thursday, August 15, resuming the world's biggest tour amid heightened security. A foiled Islamic State-inspired attack forced the cancellation of concert dates in Vienna last week.

British police said there were no concerns about the five appearances going ahead at Wembley Stadium, where 90,000 "Swifties" are expected to cheer on the star each night. However, security has been increased, the BBC reported.

Tay-gating, the practice of gathering outside a Taylor Swift show without a ticket, as thousands did in Munich earlier in the summer, will not be allowed as authorities try to minimize the more difficult-to-control vulnerabilities outside the stadium.

Wembley fans will enter through metal detectors and are only allowed to carry one small bag. Glass and metal containers, laptops and umbrellas are prohibited.

"Anyone loitering outside the stadium will be moved by security," Wembley said on its website.

Swift, 34, has said over the years that her biggest fear is the risk to her fans after two attacks at music events in 2017 - a shooting in Las Vegas and a suicide bombing at an Ariana Grande concert in Manchester, England.

The "Cruel Summer" singer will return, fueled by the soulful lyrics and sequined outfits that made her a global megastar.

She performed in Britain in June to huge crowds of fans, including Crown Prince William and two of his children, plus Keir Starmer, who was later elected Prime Minister.

Her 'Eras' tour is expected to gross over $1 billion. The final performance will be in Canada in December. I BGNES
