In a widely anticipated move, Iran has launched an aerial attack into Israel.

The Israel Defence Force estimates Iran launched over 200 different kinds of drones, including killer drones, ballistic missiles and cruise missiles.

Waikato University Law Professor Al Gillespie says this attack was to be expected, as both sides had been 'goading' each other for the past few months.

"I think the final provocation was the attack on the consulate, it was the bit that tipped them over the edge. And Iran felt they had to respond, because the provocation was too much."
