LONDON—The brother of a man who detonated a suicide bomb at the end of an Ariana Grande concert in the English city of Manchester more than three years ago has admitted to playing a full part in planning the attack, an inquiry was told on Monday.
Hashem Abedi was found guilty in March of murder, for encouraging and helping his brother Salman to blow himself up at the Manchester Arena as parents arrived to collect their children at the end of a May 2017 show by the U.S. pop singer.
