Austrian Interior Minister Gerhard Karner said a third teenager has been arrested in connection with the foiled attack on now-canceled Taylor Swift concerts in Vienna.

Chemical substances and technical devices were found at the house of a 19-year-old Austrian suspected of planning an attack on upcoming Taylor Swift concerts in Vienna.

A major rescue operation with dog handlers and helicopters is underway after a large avalanche in Austria has reportedly buried several people.

Police say gunmen with rifles opened fire in six locations and at least one person was killed. Authorities say one gunman was shot and killed by police, but they are searching for at least one other.
