The gunmen who allegedly carried out a deadly attack on a Jewish festival at Bondi Beach last week threw four undetonated explosives at the start of the attack, including a "tennis ball bomb", according to newly released documents, BBC reported. 

Naveed Akram, 24, has been charged with dozens of offences including 15 counts of murder over the attack at a Hanukkah celebration on 14 December. Akram, who was shot by police during the attack, was released from hospital on Monday and transferred to a prison.

The second alleged gunman, his father Sajid Akram, was shot dead, according to BBC.
