Britain is complaining to Spain after a minor boat collision off Gibraltar, the latest incident in a spat over the disputed territory.
The defence ministry says a Spanish police boat "manoeuvered in a dangerous and provocative manner" near Royal Navy ships within Gibraltar's territorial waters and struck one of them on Wednesday. The collision was "minor" and "no damage or injuries were sustained," according to a statement on Friday.
It's a public holiday in Spain and government offices weren't answering repeated calls seeking comment.
Tension has grown after Gibraltar built an artificial reef that Spain says damages its fishermen. Spain retaliated by beefing up border security, creating delays.
Spain ceded sovereignty of Gibraltar to Britain in 1713, but has persistently sought to regain the tiny southern territory.
