The UK government has protested to Spain about long delays at the border with Gibraltar.
The Gibraltar government had said Spain created "deliberate hold-ups" to traffic travelling to and from the British territory and Spain over the weekend and Friday.
Foreign Secretary William Hague called the Spanish Foreign Minister on Sunday to express "serious concerns".
Spain disputes UK sovereignty over Gibraltar, which has been ruled by Britain since 1713.
