The pregnant wife of a Sri Lanka bomber detonated a suicide vest when police raided the affluent family’s home in the wake of the terror attacks, killing her own children.
Abdul Lathief Jameel Mohamed studied in the UK before doing postgraduate study in Melbourne.
Prime Minister Scott Morrison did not identify the man, but said he had lived in Australia with his wife and child on a student visa and left in 2013.
Sri Lanka’s deputy defence minister Ruwan Wijewardene told a press conference most of the suicide bombers were well-educated and from wealthy families.
Some had law degrees, and all were Sri Lankan, he added.
