> Cyprus, an EU country
RAF base is on "sovereign British land", A vestige of colonialism. Technically not EU.
This is correct.
> the Sovereign Base Areas of Akrotiri and Dhekelia (SBA), is a British Overseas Territory that consists of two separate areas on the island of Cyprus.
I see the headline's now been changed to "RAF base in Cyprus hit by drone strike"
The Telegraph is, of course, strongly anti-EU, so the original headline might well have been a form of shit-stirring - "look how weak the EU are being by not retaliating!", or something along those lines.
