Stormy weather delayed the start of the World Athletics Championships in Budapest on Saturday.
A storm predicted to last 90 minutes resulted in the men's 20km walk being pushed back by two hours while action in the stadium was delayed by an hour.
The opening track and field event, qualifying for the men's shot put – an event picked out as a highlight by World Athletics president Sebastian Coe – will get underway at 0930GMT.
The championships run from Saturday to 27 August.
