Additionally, updates, photos, emergency contact numbers and resources for those looking to lend a helping hand can be found on the social media site. Users should be wary when sifting through links for updates, however.

Twitter is also being used as a resource for people frantically searching for festival attendees, though Buzzfeed has warned that a number of false missing persons reports and updates on the situation appear to be cropping up on the site.

Those who don't see social media updates from friends and relatives potentially affected by the deadly shooting are being urged by the Las Vegas Metropolitan Police Department to call 1-866-535-5654.

Police have yet to release names of those killed or injured in the Route 91 Harvest Festival shooting. It remains unclear how many are missing at this time.

The shooting began shortly after 10 p.m. as country superstar Jason Aldean performed.

Stephen Paddock, the man identified as the shooter, was confirmed dead at about midnight. He's said to have carried out the attack from his room on the 32nd floor of the Mandalay Bay Hotel and Casino, not far from where the concert was taking place.

Investigators are still searching for more information about the tragedy.
