Ellen DeGeneres, Tyler Oakley and Tom Daley are among the LGBT celebrities weighing in on Monday's horrific bombing at an Ariana Grande concert in Manchester, England.

The blast killed nearly two dozen concert-goers, including an eight-year-old girl. ISIS has claimed responsibility for the massacre. Authorities on Tuesday released the name of the suicide bomber, Salman Abedi. Police believe he had help building his bomb, which consisted of a home-made device packed with nuts and bolts.
