Following the weekend news that one of Turkey's F4 Phantoms was shot down by Syria - Turkey say in international airspace and Syria contending it was in it's airspace - Turkey has now invoked Article 4 of NATO's charter, under which consultations can be requested when an ally feels territorial integrity, political independence or security is threatened.
Turkey's Foreign Minister Ahmet Davutoglu saying, "Our plane was shot down in international airspace, 13 nautical miles (24km) from Syria"
(According to international law, a country's airspace extends 12 nautical miles ( ) from its coastline, corresponding with its territorial waters).
On the plus side for now, at least, Turkey is not seeking to invoke Article 5 of the NATO treaty which would require countries to offer it practical military assistance. However Turkey has has promised that there will be a strong, decisive and legitimate response to this incident
What's clear is that Turkey's concern is shared by other Nato countries. Foreign Secretary William Hague has expressed his grave concern at the shooting down of the aircraft, which he says, according to the Turkish authorities, had happened "without warning". Adding, "It will be held to account for its behaviour. The UK stands ready to pursue robust action at the United Nations Security Council"
What this episode does do is to highlight the escalating dangers as the Syrian crisis continues. As the bloodshed grows and the Assad regime becomes more desperate, so the risk of some untoward event happening which widens the circle of conflict grows accordingly.
As an aside, Akrotiri and Dhekelia are United Kingdom's Sovereign Base Areas (SBAs) on Cyprus and unlike other British Overseas Territories are responsible to the British Ministry of Defence rather than the Foreign and Commonwealth Office, plus they contain the only full-fledged Royal Air Force air base in the Mediterranean and which is significantly closer to Syria than Italy was to Libya.
Perhaps a story to watch with interest, especially now that there's a Syria/Turkey aspect
