A deadly blast took place at an Ariana Grande concert Monday night in Manchester, England.

Ariana Grande spoke out hours after an explosion following her concert Monday night killed at least 22 people and injured many others.

"Broken," the pop star tweeted at 3:41 a.m. local time in U.K. "From the bottom of my heart, i am so so sorry. i don't have words."

A deadly explosion outside the Manchester venue Grande was performing at is believed to be the work of terrorists, police said Monday. Grande, who was just finishing her performance when the explosions happened around 10:35 p.m. local time, was not injured.

Grande's manager Scooter Braun also released a statement via Twitter. "Tonight, our hearts are broken. Words cannot express our sorrow for the victims and families harmed in this senseless attack," he said.

Braun continued, “We mourn the lives of children and loved ones taken by this cowardly act. We are thankful for the selfless service tonight of Manchester’s first responders, who rushed towards danger to help save lives. We ask all of you to hold the victims, their families and all those affected in your hearts and prayers.”

The Greater Manchester Police Department reported via Twitter that the agency is treating the incident as a terror attack until proven otherwise. British authorities are focusing on the attack as a possible suicide bombing, according to a U.S. law enforcement official briefed on the matter.
