US pop star Mariah Carey said on Friday that she was canceling a tour stop in Brussels amid safety concerns following attacks this week that killed 31 people and injured some 270 more. The songstress, one of the best-selling female solo artists of recent times, was slated to perform in the now-racked Belgian city on Sunday as part of her 'Sweet Sweet Fantasy' European tour. 'I love my fans in Brussels and at this time I am being advised to cancel my show for the safety of my fans, my band, crew and everyone involved with the tour. I hope to see you soon and send my prayers and eternal love,' she said in a statement on her Twitter account. Carey, perhaps best known for her 90s hits like 'Hero,' 'Fantasy,' and 'Always Be My Baby,' is set to wrap up her tour with back-to-back performances in Johannesburg in May.
