THE Gibraltar Government will report every Spanish incursion into its territorial waters to the UN, in the latest chapter in a growing feud between the two powers.

The announcement came after a Spanish vessel conducting oceanographic research strayed into Gibraltarian waters, accompanied by three patrol boats from the Spanish Guardia Civil.

The Royal Navy and the Royal Gibraltar Police challenged the vessels’ crew, leading to a dispute during which the crew claimed to be operating within Spanish territory.

A spokesperson for the Rock said: “The Government takes a very serious view of the continuing incursions by Spanish state vessels into British Gibraltar territorial waters.”
