The mother of an extremist inspired by so-called Islamic State who stabbed shoppers in a New Zealand supermarket said her son was radicalised by neighbours from Syria and Iraq who helped him recover from an injury.

The attacker, Ahamed Aathil Samsudeen, was a 32-year-old Tamil Muslim from Sri Lanka.
