The coalition, whose official name is the National Coalition of Syrian Revolutionary and Opposition Forces, was formed at a meeting in Qatar earlier this month, and has already been anointed with official recognition from Britain, France, Turkey and the members of the Gulf Cooperation Council. But in order to encourage further recognition internationally, it must tackle the broader problem of uniting multiple groups in exile and rebels on the ground in Syria.
That challenge was apparent on the first day of what are expected to be two days of talks in Egypt. Disagreements emerged over the composition of the coalition when the Syrian National Council, one of its members, tried to increase the number of its representatives.
“Nothing will proceed until we work this out,” said one council member at the talks, who spoke to Reuters on condition of anonymity.
The talks took place against the backdrop of a 20-month civil war in which about 40,000 people have been killed so far in clashes between armed rebels and jihadist forces on one side and Mr. Assad’s military on the other. The conflict has flared at various times along Syria’s borders with Lebanon, Israel, Turkey and Jordan and in most of the country’s cities, including deadly car bombings on Wednesday near Damascus, the capital.
In Turkey, once an ally of the Assad government, a team of NATO inspectors visited sites on Wednesday where the alliance might install batteries of Patriot antiaircraft missiles that Turkey, a member, has requested to prevent any incursions by the Syrian air force, which has become the Assad government’s main weapon against the rebels. Patriot missiles have also been discussed as a way of enforcing a no-fly zone over rebel-held areas of Syria near the Turkish border if one is imposed.
Meanwhile, opposition politicians gathered in a Cairo hotel to shape an alternative government. Ahmad Ramadan, a member of the national council, said in an interview with Radio Sawa, an Arabic-language broadcaster sponsored by the United States government, that the talks were more likely to decide on the selection process than to choose actual candidates.
Khaled Khoja, a coalition member attending the talks, said: “I don’t think we’ll be discussing the election of a transitional government during the meeting today. We’re still discussing whether to have a government or to have committees instead.”
State media said on Wednesday that at least 34 people, and possibly many more, died in the two car bombings in Jaramana, a suburb of Damascus that is populated by minorities.
The official SANA news agency said the explosions struck at about 7 a.m. and were the work of “terrorists,” the word used by the authorities to denote rebel forces seeking the overthrow of President Assad.
The agency said the bombings were in the main square of Jaramana, which news reports said is largely populated by members of the Christian and Druse minorities. Residents said the neighborhood was home to many families who have fled other parts of Syria because of the conflict and to some Palestinian families. The blasts caused “huge material damage to the residential buildings and shops,” SANA said.
The death toll was not immediately confirmed. An activist group, the British-based Syrian Observatory for Human Rights, initially said that 29 people had died but revised the figure later to 47, of whom 38 had been identified. Of the 120 injured, the rebel group said, 23 people were in serious condition, meaning that the tally could climb higher.
There were also reports from witnesses in Turkey and antigovernment activists in Syria that for the second successive day insurgents had shot down a government aircraft in the north of the country, offering further evidence that the rebels are seeking a major shift by challenging the government’s dominance of the skies. It was not immediately clear how the aircraft, apparently a plane, had been brought down.
Video posted on the Internet by rebels showed wreckage with fires still burning around it. The aircraft appeared to show a tail assembly clearly visible jutting out of the debris. Such videos are difficult to verify, particularly in light of the restrictions facing reporters in Syria. However, the episode on Wednesday seemed to be confirmed by other witnesses.
“We watched a Syrian plane being shot down as it was flying low to drop bombs,” said Ugur Cuneydioglu, who said he observed the incident from a Turkish border village in southern Hatay Province. “It slowly went down in flames before it hit the ground. It was quite a scene,” Mr. Cuneydioglu said.
Video posted by insurgents on the Internet showed a man in aviator coveralls being carried away. It was not clear if the man was alive but the video said he had been treated in a makeshift hospital. A voice off-camera says, “This is the pilot who was shelling residents’ houses.”
The aircraft was said to have been brought down while it was attacking the town of Daret Azzeh, 20 miles west of Aleppo and close to the Turkish border. The town was the scene of a mass killing last June, when the government and the rebels blamed each other for the deaths and mutilation of 25 people. The video posted online said the plane had been brought down by “the free men of Daret Azzeh soldiers of God brigade.”
On Tuesday, Syrian rebels said they shot down a military helicopter with a surface-to-air missile outside Aleppo and they uploaded video that appeared to confirm that rebels have put their growing stock of heat-seeking missiles to effective use.
In recent months, rebels have used mainly machine guns to shoot down several Syrian Air Force helicopters and fixed-wing attack jets. In Tuesday’s case, the thick smoke trailing the projectile, combined with the elevation of the aircraft, strongly suggested that the helicopter was hit by a missile.
Rebels hailed the event as the culmination of their long pursuit of effective antiaircraft weapons, though it was not clear if the downing on Tuesday was an isolated tactical success or heralded a new phase in the war that would present a meaningful challenge to the Syrian government’s air supremacy.
