Guardia Civil vessel is escorted out of Gibraltar waters after an early morning incursion

A Guardia Civil boat entered Gibraltar waters and blared its siren early this morning - with residents of nearby Waterport Terraces complaining of the noise.

In response to GBC questions, the Convent said it's aware of an incursion by a Spanish vessel.

It says this was challenged by a Gibraltar law enforcement vessel to ensure it left British Gibraltar waters.

A spokesperson said the Foreign, Commonwealth and Development Office makes formal diplomatic representations to Spain where appropriate.

They restated the FCDO's position that incursions are a violation of UK sovereignty, not a threat to it.

For his part, the Chief Minister told GBC the Government was seeking further details on the incident.

However, Fabian Picardo described the Guardia Civil's actions as "unconscionable".
