With the terror alert raised to maximum in Brussels, Belgium, the public is being warned to avoid areas with high concentrations of people.
That means places of high commercial concentration, train stations, major events, public transport and concerts.
Concerts like the one Kalle Mattson was supposed to play in Brussels today.
Mattson, a Sault born musician who won SOCAN's Songwriter of the Year and four Northern Ontario Music Award's for Album of the Year and Songwriter of the Year in both 2012 and 2015, is currently on tour to support his latest release, Avalanche, and was scheduled to play the Botanique today.
Instead, police are asking people in Brussels to shelter in place.
"Due to terror alert Level 4 being announced today in #Brussels, Botanique has decided to postpone my show tonight," says Mattson on his Facebook page. "Scary stuff but really looking forward to coming back sometime next year. Stay safe everyone!"
International news sources say the last surviving Paris jihadist, Salah Abdeslam has been spotted in Brussels, the city he was said to be living in before the deadly attack just over a week ago that left 129 people dead and at least 350 injured.
Sources report Abdeslam is on the run from police and from ISIS after he fled Paris when his suicide vest failed to detonate.
