1.5m Olympic tickets go on sale

Another round of olympic ticket sales is underway this morning.

More than 1.5m are available for football, volleyball and freestyle wrestling on a first-come first-served basis.

They're on offer to the 700,000 applicants who got all or part of their ticket requests in the first-round sale which closed in April.

But anyone who tried to get tickets in the second round can't try again.
