Breaking News: Gunmen Planned, Practised Attack, Threw Explosives at Bondi: Police

Two men, Naveed Akram and his father Sajid Akram, allegedly carried out a deadly attack on a Jewish festival at Bondi Beach last week. Naveed Akram, 24, has been charged with dozens of offences, including 15 counts of murder.

According to police, the pair threw four undetonated explosives at the start of the attack, including a "tennis ball bomb". They also allegedly practised shooting weeks before the attack and recorded a video manifesto in October, sitting in front of the Islamic State group flag.

Police allege the Akrams meticulously planned this terrorist attack for many months. Videos found on Naveed's phone show his father conducting firearms training. The pair were seen carrying "bulky items" hours before the attack, according to CCTV footage.

Naveed Akram was shot by police during the attack and has since been released from hospital and transferred to a prison. His father, Sajid Akram, was shot dead.

This is a developing story. Police continue to investigate the attack and the motives behind it. Further charges and developments are expected in the coming days.
