What can we tell from Iran plane footage?

Iran has again rejected suggestions that it shot down a Ukrainian passenger jet near its capital, Tehran, on Wednesday. Western leaders have claimed that evidence suggested the plane had been hit by a surface-to-air missile, possibly by mistake. Videos of the plane in its final moments have been circulating online, so what can we tell from that footage?

Also, we go to Australia where authorities are warning that strong winds have fanned two massive bushfires into a 'mega blaze'. We speak to our weather team and hear from a farmer affected by the fires.

And we get international reaction to Prince Harry and Meghan's decision to step back from their roles as senior members of the Royal Family.
