The alleged gunmen behind the Australia's Bondi beach attack are a father-son duo suspected of using legally obtained firearms to commit the massacre, according to police.

Axar.az informs, citing Guardian, Naveed Akram, 24, was arrested at the scene and taken to a Sydney hospital with critical injuries. His 50-year-old father, who the Sydney Morning Herald first reported to be Sajid Akram, was shot dead by police. Police would not confirm their names.

The pair allegedly killed 15 people, with dozens more injured in the shootings which took place on Sunday, during a gathering to celebrate the first night of Hanukah.

A 10-year-old girl was among the dead in Australia’s worst mass shooting for almost 30 years, while 42 more were rushed to hospital with gunshot wounds and other injuries.
