Los Angeles, Oct 3 (IANS): Rapper Future was slammed by social media users for promoting his Halloween concert in Las Vegas just 12 hours after the massacre in which at least 59 people died and over 500 were injured.

The 33-year-old Grammy nominee, last seen in Australia on Sunday, came under fire after he or someone from his team posted a flier for his October 28 gig at Drai's, Las Vegas, on Twitter and Facebook, reports dailymail.co.uk. 

One user wrote: "All the s*** going on in Vegas right now. Take some time from thinking about yourself and promoting a concert in Vegas", and another also shared: "Too early bro".

In one of the deadliest mass shootings in American history, a gunman in a high-rise hotel in Las Vegas opened fire on a huge outdoor concert festival, killing 59 and injuring 527.

Stephen Paddock, 64, opened fire with automatic weapons on some 22,000 people at the Route 91 Harvest concert from the 32nd floor of the Mandalay Bay Resort and Casino on Sunday at around 10.30 p.m. Paddock killed himself as special response team officers broke into the hotel room.

Many of America's most influential celebrities like Lady Gaga, Ariana Grande, Amy Schumer, Billy Eichner, Lena Dunham, Mia Farrow, Ben Platt, Julianne Moore, Jessica Chastain, John Legend and Kim Kardashian West are using their social media platforms to push for change and plead for gun control.
