LOS ANGELES, May 24 (Reuters) - U.S. singer Ariana Grande has suspended her concert tour after a suicide bomber killed 22 people at her concert in Manchester, England, the singer's representatives said on Wednesday.

Grande was scheduled to perform two shows at London's O2 arena this week as part of her "Dangerous Woman" tour. Both shows have been canceled, as well as performances through June 5, according to a statement from the singer's record label.
