Syria said it engaged the aircraft in its airspace "according to the laws that govern such situations"
Turkey
has called a meeting of Nato member states to discuss its response to
the shooting down of one of its warplanes by Syrian forces on Friday.
Ankara has invoked Article 4 of Nato's charter, under which
consultations can be requested when an ally feels their security is
threatened, officials say.
Earlier, Turkey's foreign minister said the F-4 Phantom was in international airspace when it was shot down.
Syria has insisted the jet was engaged while it was inside its airspace.
It has also said no act of hostility was intended, noting
that as soon as the military discovered the "unidentified" aircraft was
Turkish its navy joined efforts to rescue the two crew members.
The Turkish foreign ministry said it knew the coordinates of
the jet, which was in Syrian territorial waters at a depth of 1,300m
(4,265ft), but has not yet found it.
The coast guard is still searching for the crew in the Mediterranean Sea, though hopes are fading of them being found alive.

Turkey's decision to call a Nato meeting to discuss the
downing of one of its warplanes by Syrian air defences is a measure of
the seriousness of the situation. But it also sends a signal that, for
now, Ankara is looking for a concerted diplomatic response rather than
taking military action of its own.
Article 4 of the North Atlantic Treaty allows for countries
to consult together whenever "in the opinion of any of them, the
territorial integrity, political independence or security of any of the
parties is threatened".
Turkey might have sought such consultations at earlier stages
in the Syrian crisis, prompted for example by the flood of refugees
across its borders or shells fired by Syria landing on its territory.
Nato's deliberations will raise the pressure on the Syrian
regime, but it is hard to see them having any practical effect in terms
of convincing President Bashar al-Assad to relinquish power.
The government has also issued a diplomatic protest note to Syria.
'Training mission'
Nato spokeswoman Oana Lungescu said the North Atlantic
Council, the principal political decision-making body within the
military alliance, would meet in Brussels on Tuesday to discuss the
incident.
"Turkey has requested consultations under
Article 4 of Nato's founding Washington Treaty," she told Reuters.
"Under article 4, any ally can request consultations
whenever, in the opinion of any of them, their territorial integrity,
political independence or security is threatened."
Turkey wants to be sure of the strongest backing once it
decides its official response, reports the BBC's Jonathan Head in
Istanbul.
The government has promised that it will be strong, decisive
and legitimate, and that it will share all the information it has with
the public.
Earlier, Foreign Minister Ahmet Davutoglu became the first
senior Turkish official to challenge Syria's account of the downing of
the jet.
After lengthy meetings with military chiefs, he told TRT
state television that the unarmed jet had "momentarily" entered Syrian
airspace by mistake on Friday but had left when it was shot down 15
minutes later.
"According to our conclusions, our plane was shot down in international airspace, 13 nautical miles (24km) from Syria," he said.
Foreign Minister Ahmet Davutoglu said the aircraft was unarmed, and on a routine training mission
According to international law, a country's airspace extends 12
nautical miles (22.2km) from its coastline, corresponding with its
territorial waters.
Mr Davutoglu also insisted that the jet had not been on a
"covert mission related to Syria" but had instead been carrying out a
training flight to test Turkey's radar capabilities.
He said the plane had not "shown any hostility", been clearly
marked as Turkish, and that he did not agree with the Syrian military's
statement that it had not known to whom it belonged.
UK Foreign Secretary William Hague said the Syrian military's
actions were "outrageous" and underlined "how far beyond accepted
behaviour the Syrian regime has put itself".
"It will be held to account for its behaviour. The UK stands
ready to pursue robust action at the United Nations Security Council,"
he said.
'Unidentified target'
The Turkish military said it lost radio contact with the F-4
Phantom at 11:58 (08:58 GMT) on Friday while it was flying over Hatay
province, about 90 minutes after it took off from Erhac airbase in the
province of Malatya, to the north-west.
Later, the Syrian military said an "unidentified air target"
had penetrated Syrian airspace from the west at 11:40 local time (08:40
GMT), travelling at very low altitude and at high speed.
It said that in line with the laws prevailing in such cases,
Syrian air defences engaged the craft, and scored a direct hit about 1km
(0.5 nautical miles) from its coastline.
It burst into flames, and crashed into the sea at a point
10km (5 nautical miles) from the village of Om al-Tuyour, off the coast
of Latakia province, well within Syrian territorial waters, the
statement added.
Relations between Nato-member Turkey and Syria, once close
allies, have deteriorated sharply since the uprising against Syrian
President Bashar al-Assad began in March 2011. More than 30,000 Syrian
refugees have fled the violence across the border into Turkey.

under international law is considered international airspace
