BAB AL-SALAM, Syria — When Syrian rebels stopped two buses of Lebanese travelers in the spring and took 11 passengers hostage, they set off a cascade of fallout: riots at the Beirut airport, retaliation kidnappings against Syrians in Lebanon and a deepening of the sectarian character of the war.
Since that day in May, as civil war has raged and opposition fighters have gained momentum in their bid to oust President Bashar al-Assad, the rebels have continued to detain most of their prisoners, having released two as a good-will gesture. The rest, nine men who the captors insist are members of Hezbollah — which the prisoners deny — will be released only as part of a prisoner exchange, the rebel commander holding the group said.
The commander, Amar al-Dadikhi of the North Storm brigade, which has been holding the prisoners at an undisclosed location in Syria’s northern countryside, said in interviews that he would free the hostages if the Syrian government released two prominent opposition figures and if Lebanon freed all Syrian activists in government custody.
The men’s prospects for freedom, he said, are “in the Syrian government’s hands, and the Lebanese government’s hands.”
Their detention began after they were removed at gunpoint from buses driving though Syria while returning from a Shiite religious pilgrimage to Iran. The case has remained stubbornly unresolved, even as it has raised questions about the character and criminality of some of the rebels whom the West has hesitatingly backed.
The hostage-taking also sullied the reputation of the Free Syrian Army, the loosely organized antigovernment fighting groups. Without any public evidence to support the claim that the hostages are members of Hezbollah, the case has exposed the limits of the Free Syrian Army’s influence over rebels who fly its banner.
The Free Syrian Army’s leadership appears not to have been able to persuade Mr. Dadikhi to release the men, even as it seeks international recognition and tangible military aid, two desires undermined by the hostage case.
Mr. Dadikhi, a large and scarred man who is alternately praised by many opposition activists for battlefield bravery and whispered about as an accomplished smuggler who once maintained extensive ties to the government, claims to have 1,300 armed fighters and a network of cross-border contacts. His control of the border crossing that leads to Aleppo, Syria’s largest city, makes him a power broker by default.
Col. Abdul Jabbar al-Okaidi, a former Syrian military officer and one of the Free Syrian Army commanders in the Aleppo region, declined to comment on the case beyond saying that he was aware of the demands of Mr. Dadikhi, whom he called Abu Ibrahim.
“Abu Ibrahim has his requests,” he said. “If they are taken care of, he will free the Lebanese.”
Relatives of the hostages, reached by telephone in Beirut, expressed deep anger upon hearing Mr. Dadikhi’s demands. “Let them capture someone from the regime. Why abduct Lebanese? What do we have to do with the revolution?” said the wife of one of the hostages. “They are liars; they won’t release them. It is just blackmail.”
Mr. Dadikhi allowed two journalists from The New York Times to meet with two of the hostages — Ali Abass, 30, and Ali Tormos, 54 — for about 30 minutes on Thursday afternoon. The men appeared to be in good health, and they said they and the other hostages had not been harmed.
They expressed weariness and asked that Lebanon and Syria meet their captors’ demands. “It has been a long time, and we want to go home,” Mr. Abass said.
The interview was held in a former government office at the border crossing from Syria to Kilis, Turkey. Mr. Dadikhi agreed to leave the room while the hostages spoke. The meeting remained all but scripted.
