The Australian government has announced a gun buyback scheme in the wake of the Bondi Beach attack - its deadliest mass shooting in decades, BBC reported. 

The scheme is the largest since the Port Arthur massacre in 1996, which left 35 people dead and prompted Australia to introduce world-leading gun control measures.

Fifteen people were killed and dozens injured on Sunday when two gunmen, believed to have been motivated by "Islamic State ideology", opened fire on a Jewish festival at the country's most iconic beach, according to BBC.
