NATO leaders will meet this week to discuss how and whether to respond to Syria's downing of a Turkish jet in what Turkey insists was international airspace. The incident has spiked regional tensions caused by the conflict in Syria, where reports Sunday said more than a dozen people died in new clashes between rebels and regime forces.
The jet's wreckage was found in the Mediterranean at a depth of 4,265 feet (1,300 meters), Turkey's state-run Anadolu Agency said Sunday. The two pilots remain unaccounted for.
Turkish Foreign Minister Ahmet Davutoglu said the jet was on a training flight to test Turkey's radar capabilities, not spying on Syria. He said the plane mistakenly strayed into Syrian airspace Friday, but was quickly warned to leave by Turkish authorities and was a mile inside international airspace when it was shot down off the coast of Latakia.
Syria insisted Saturday that the shooting was "not an attack" and that the aircraft had violated its airspace.
Oana Lungescu, a NATO spokesman, said Sunday that at the request of Turkey, the alliance's governing body will meet Tuesday to discuss the incident. The consultations will focus on article 4 of NATO's founding Washington Treaty
"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," Lungescu said. The North Atlantic Council - the ambassadors of the 28 NATO countries - will decide whether to respond, she said.
The last time article 4 was invoked was nine years ago - also by Turkey - after tensions with neighboring Iraq escalated. However, that case did not lead to the invocation of article 5, which declares that an attack against any single NATO country shall be considered as an attack against them all.
Turkey has been one of the most vociferous critics of Syrian President Bashar Assad's regime as it has cracked down on an increasingly armed popular uprising. Opposition activists say the conflict has killed 14,000 people, most of them civilians, over the past 15 months.
Turkish Prime Minister Recep Tayyip Erdogan, who discussed the plane's downing with leaders of opposition parties in Parliament on Sunday, was expected to make a statement on Tuesday, Davutoglu said.
The plane's downing has already drawn international criticism from other countries pushing Assad to stop his crackdown.
British Foreign Secretary William Hague said Sunday he was "gravely concerned by the Syrian regime's action in shooting down" the plane and that Davutoglu had told him no warning was given.
"This outrageous act underlines how far beyond accepted behavior the Syrian regime has put itself, and I condemn it wholeheartedly," Hague said in a statement. "The Assad regime should not make the mistake of believing that it can act with impunity. It will be held to account for its behavior."
Hague met last week with United Nations and Arab League special envoy Kofi Annan for talks on plans for an international summit, while British officials discussed the issue in Geneva on Saturday with members of Annan's team. Hague noted Sunday that "The UK stands ready to pursue robust action at the United Nations Security Council."
In Syria, state-run SANA news agency said gunmen infiltrating from Turkey clashed with Syrian border guards in Rabiah, a region in the coastal Latakia province. SANA said several infiltrators died in the late Saturday clash, while others reportedly returned to Turkey. It said several Syrian border guards were wounded, but didn't specify how many.
Turkey denies sheltering armed Syrian rebels, although many Syrian refugees have fled to camps on the Turkish side of the border.
Syrian activists, meanwhile, said rebels captured a military base in the northern Syrian province of Aleppo, confiscating large amounts of ammunition. The Britain-based Syrian Observatory for Human Rights said 16 government troops died in the attacks on the base near the rebel-held town of Daret Azzeh and nearby checkpoints early Sunday.
Area activist Mohammed Saeed said the rebels had removed hundreds of artillery shells from the base. Saeed added via Skype that troops retaliated with intense shelling on the area using helicopter gunships.
On Friday, state media said 25 people were kidnapped by "terrorists" and killed in Daret Azzeh. Activists said the 25 killed were pro-regime gunmen known as shabiha.
Also on Sunday, Syrian opposition groups met in Brussels to hash out differences and plan for a democratic transition. The disparate groups are divided over whether outside military intervention would help or hurt and whether to engage in dialogue with Assad's regime. The conference, attended by some 50 people, will continue Monday.
Jordanian Information Minister Sameeh Maaytah, meanwhile, said Sunday that three other Syrian pilots had defected last week, even before a pilot flew his warplane into neighboring Jordan. He said the other three crossed overland into Jordan. He was unsure if the four pilots knew each other or had coordinated their escape from Syria.
