Hours after a country-music festival in the heart of the Las Vegas Strip became the deadliest mass shooting in U.S. history, the city has set up a phone line for those searching for loved ones.

More than 50 people were killed and more than 400 were injured in the onslaught outside the Mandalay Bay hotel-casino. The Route 91 Harvest music festival reportedly drew more than 30,000 concertgoers.

Family and friends looking for loved ones can call (866) 535-5654 in the hopes of obtaining a status.

In an Instagram post, the city described the bloodshed as being a “horrific night in Las Vegas that has left us all in shock.”

The post also said that two neighboring United Blood Services facilities are holding blood drives.

Facebook introduced a check-in feature Monday morning that allows those in the area to notify their friends that they are safe.

In addition, a crisis response page featuring posts from community members and concerned out-of-state residents is a collection of donation, service and housing opportunities.

A GoFundMe account for the victims and their families set up by Clark County Commission Chair Steve Sisolak had reached more than $135,500 as of 9:30 a.m. Monday.
