The gunmen accused of carrying out the Bondi Beach attack used a “tennis ball bomb” among other explosives and practised shooting for weeks before the massacre, new court documents say.
Police allege the two gunmen were father-and-son duo Sajid and Naveed Akram. While Sajid Akram was shot dead by police, 24-year-old Naveed has been charged with 15 counts of murder over the attack targeting a seaside Hanukkah celebration on 13 December.
