Naveed Akram’s phone included videos showing him and his father standing in front of an Islamic State flag, making statements expressing extremist ideology and criticising “Zionists”.

“We, as a Jewish community, have been abandoned and left alone by our government”.

Naveed Akram has been charged with one count of committing a terrorist act, 15 counts of murder, and 40 counts of causing wounding or grievous bodily harm with intent to murder.

One gunman was shot dead at the scene, while the second remains in custody in critical condition.
