A security alert in Magilligan, County Londonderry, has ended with nothing untoward being found, police have said.

Motorists and members of the public were asked to avoid the area as police conducted a public safety operation.
A ferry service between Magilligan Point and Greencastle, County Donegal, in the Republic of Ireland, was also disrupted for a time.
