During the final show of her six-performance London residency at the O2 Arena on Tuesday night, Adele dedicated a song to the victims of the Brussels terror attacks. After the "Hello" singer implored the crowd of the maximum-capacity stadium to hold their illuminated cell phones in the air, she began singing a heartfelt rendition of the song, "Make You Feel My Love." Watch the video above. 

Three bombs were detonated in Brussels, the Belgian capital, on Tuesday morning, killing 34 people and wounding at least 230 more, according to the New York Times. Security measures throughout the European Union have been raised in response to the attacks, while some high-profile celebrity events have been cancelled. Adele's concert, on the other hand, was permitted to proceed.
