Overseas now in the US has claimed its latest strikes against Iran were in self-defence.

US Military Central Command spokesperson Tim Hawkins says, quote, targets included missile launch sites and Iranian boats attempting to emplace mines.

This latest attack by the US comes despite a ceasefire officially in place between America and Iran since the 8th of April and ongoing talks between the countries to end the conflict.

It also comes just days after US President Donald Trump had announced a peace deal between the US and Iran was largely negotiated to then change his tune to instruct negotiators to not rush into a deal.

Meantime, news of the US attacks on Iran shook the local share market with shares in the ASX tumbling while the oil price is on the increase, making back some of its overnight falls.

And vivid Sydney's drone show, a centrepiece of the city's iconic harbourside light spectacle, has been cancelled for the next few days.

It follows a serious malfunction which saw dozens of drones fall from the sky on Monday night because of a malfunction.

Organisers believe there was an issue with the radio frequency which caused the malfunction, which did not happen during pre-flight checks, site visits or the rehearsals.

Vivid Sydney says it would cancel the drone shows both tonight and tomorrow night to allow for a full assessment.

Now it's time for our deep dive into MND.

Yesterday, former AFL great and charity campaigner Neil Danaher passed away after a 15-year battle with this cruel disease.

After being diagnosed, he helped raise around $100 million for research into MND that takes away your ability to walk, talk, swallow and eventually breathe.

To explain the risk factors and why genetics also play a role is Claire Sullivan, the CEO of MND Australia.

Claire, thanks so much for joining us.

First, our sincere condolences, the loss of Neil Danaher.

He was a giant on so many levels.

How is everyone feeling today?

If there is ever any silver lining, Neil's legacy will be the fact that he's raised more than $120 million for research.

We have some of now the best researchers in the world with MND and the awareness is so much greater.

Can I ask you, Claire, what is MND?
