Apprentice Boys Parade underway in Derry

The Apprentice Boys Parade is underway in Derry.

Up to 15,000 people are taking part with 140 bands.

There are appeals for calm, from politicians on both sides of the border, as well as from the PSNI.

There was concern about a protest planned by dissident Republicans in Derry to coincide with the parade, but it was called off.
