'Cacophony of horns' at Gibraltar border as queues form

17 August 2013 Last updated at 15:56 BST

Long queues have again formed at Gibraltar's border with Spain as motorists wait to enter and exit the territory amid a growing row between the UK and Spain.

Spain has tightened border controls with the British territory, prompting the UK to threaten legal action.

Britain says the checks have been imposed in retaliation for an artificial reef installed by Gibraltar which Spain says will disrupt its fishing fleet.

The BBC's Tom Burridge reports from the queue, where many motorists have been waiting for up to three hours.
