Bomber Salman Adebi phoned his nuclear scientist mother hours before his deadly attack and said 'forgive me', a Libyan anti-terror official has said.
A Libyan security source revealed Abedi rang his younger brother Hashem in Libya, telling him to get their mother Samia Tabbal, 50, to call him.
Details of his plea for forgiveness emerged after Tabbal was quizzed by police in Tripoli.
