blink-182 were slated to perform in El Paso with Neck Deep last night on their summer tour, but they had to postpone the show following a mass shooting.

On Saturday, a man began to open fire with an AK-style semiautomatic rifle at a Walmart Supercenter, killing 20 people and injuring 26 others. Authorities are investigating the shooting, which might be a case of domestic terrorism and hate crime. The shooter, a 21-year-old white male, has been charged with capital murder, The Washington Post reports.

blink-182’s frontman Mark Hoppus tweeted from inside his hotel in El Paso on Saturday. The band was reportedly leaving breakfast when their security told them that there was an active shooter at the mall they were headed to.

“We are locked down in our hotel in el paso,” he said in the tweet. “Over the intercom system they just announced that there are reports of another active shooter directly across the street at a location different from the first shootings.”

Then, in a follow-up tweet, he updated fans noting that police confirmed that a report of a separate incident at the adjacent Bassett Mall was incorrect and a federal agent was at the door.

“Following today’s terrible tragedy in El Paso we are postponing our Sunday, August 4th show at the UTEP Don Haskins Arena in solidarity with the community,” the band tweeted that night. “Sending our love to the entire community of El Paso.”

Lil Wayne, who is currently co-headlining the summer tour with blink-182, was performing at Lollapalooza during the day of the mass shooting. A postponed date for their gig, which was supposed to take place at the UTEP Don Haskins Arena, has not been revealed at this time. blink-182 told fans to stay tuned for more updates and they are “sending our love to the entire community of El Paso.”
