BEIRUT (AP) — Rebels captured a small military base near Aleppo on Tuesday and stormed another in the same area that protects a major airport, a day after seizing Syria's largest dam.
With the back-to-back blows to President Bashar Assad's regime, opposition fighters appear to be regaining some momentum, expanding their northern zone of control while at the same time pushing deeper into the heart of the capital, Damascus.
Rebels have been attacking Aleppo's civilian airport, which remains in regime hands, for weeks. They now appear to have removed the main defenses around the facility. Civilian flights stopped weeks ago because of the intensity of the fighting.
In New York, U.N. human rights chief Navi Pillay said the number of people killed in Syria is probably now approaching 70,000. Her comments came less than six weeks after she said the death toll had exceeded 60,000, a figure that at the time she called "truly shocking."
She told the U.N. Security Council that there have probably been almost 10,000 new deaths in recent weeks. Pillay said the council's deep division and inaction over the nearly 2-year-old conflict had been "disastrous" and that civilians on all sides had paid the price.
As rebels made new conquests in the northern provinces of Aleppo and Raqqa, they also fought street by street in the eastern city of Deir el-Zour, near the border with Iraq. They were trying to capture the city, a provincial capital of an oil-rich region that carries the same name.
Rebels control wide areas in the three provinces. But if they can fully capture them, it would put them in control of the country's water and oil resources as well as wheat fields.
"If they (three provinces) fall in the hands of the rebels, it will be a strategic strike against the regime," said Rami Abdul-Rahman, who heads the Britain-based Syrian Observatory for Human Rights, an anti-regime activist group.
Abdul-Rahman said that after days of sporadic clashes around the Jarrah airfield, rebels launched a major assault on the base on Monday and had overrun the facility by Tuesday morning.
He said several regime troops in the area were killed or wounded in the fighting, while others fled as the rebels advanced. There was no word on opposition casualties.
The airfield, which is located near the Al-Furat dam captured on Monday, housed fighter jets used in airstrikes on rebel held-areas.
A video posted online by activists showed several military aircraft at Jarrah, some parked on the tarmac and another in a hanger with boxes of ammunition piled up against a wall nearby.
"These warplanes are now in the hands of Ahrar al-Sham Islamic movement," one rebel says in the video, referring to a rebel unit.
The video appeared genuine and corresponded to other Associated Press reporting on the events depicted.
The air base is located near the northeastern town once known as Tabqa. The town's name changed to Thawra, Arabic for revolution, after the Al-Furat dam was built there in the late 1960s.
Earlier this month, the Observatory said rebels seized another smaller dam in Raqqa province, the Baath dam, named after Syria's ruling party. In November, Syrian opposition fighters captured Tishrin hydroelectric dam near the town of Manbij in northern Aleppo province, which borders Raqqa.
Rebels also stormed a second base on Tuesday.
The Observatory and the Aleppo Media Center said opposition fighters captured large parts of the "Brigade 80" base near the city's main civilian airport.
The rebels were also attacking another major air base, Nairab, adjacent to the international airport and took control of al-Manara army checkpoint just outside it, the Observatory and AMC said.
The Observatory said there were dozens of casualties, adding that Syrian warplanes bombarded areas around the airport after the rebel advance.
Reporting from Aleppo, Syrian state TV correspondent Shadi Halawi said the city's international airport was "100 percent safe," although he acknowledged that rebels were able to enter the "Brigade 80" base. Government troops were pushing them out, he said.
Rebels control many areas in the north and east of the country, and hold whole neighborhoods in Aleppo, Syria's largest urban center and its main commercial hub. The government maintains a tight grip on Damascus, and several central provinces, including Homs and Hama.
For nearly a week, rebels have been trying to slowly battle their way into the capital Damascus from neighborhoods and towns on its doorstep, and have punched to within a mile of the heart of the city.
There was more fighting in the capital on Tuesday. Activists said government warplanes struck opposition strongholds in several suburbs including Zamalka and Douma.
In a rare attack, a mortar round fell outside the Homs oil refinery, killing an employee and wounding three. In addition to Homs, Syria has another oil refinery in the coastal city of Banias.
Even as the fighting intensifies, the opposition and the government are saying they are ready for a dialogue that they hope would end the crisis.
Syrian Information Minister Omran al-Zoubi was quoted by Syrian TV as saying that "the fate and future of Syrians should be decided in Damascus and by the Syrians themselves."
He was apparently responding to calls by opposition leader Mouaz al-Khatib, who said he is ready for talks with the regime in Syria as long as it is held in rebel-held territories. Al-Khatib also demanded that authorities release 160,000 detainees and renew passports of dissidents living abroad.
National Reconciliation Minister Ali Haider told reporters in Damascus that the government has fulfilled a package of measures to renew the passports of Syrians abroad and they have been put in force.
Also Tuesday, Assad attended the first meeting of the Syrian Cabinet after a minor government reshuffle two days ago. He said in comments carried on the presidency's Facebook page that the world now recognizes how steadfast his regime really is.
In Turkey, Interior Minister Muammer Guler said the death toll from an attack Monday on a border crossing between Syria and Turkey had risen to 14 from 13.
The frontier area has seen heavy fighting, although attacks on the crossings that are used by Syrian refugees and international aid agencies have been rare.
A major Syrian opposition faction accused the government of the bombing, saying it narrowly missed 13 leaders of the group, including its president.
Syrian National Council President George Sabra told reporters in Turkey on Tuesday that the car bomb went off shortly before the SNC president and 12 other members of the group's executive council drove through a border crossing with Turkey.
"We heard an explosion nearly half an hour before we reached the border crossing point," Sabra said.
There was no claim of responsibility for the blast. Turkey's deputy prime minister, Besir Atalay, said Tuesday that a preliminary investigation indicated three assailants parked a car packed with explosives in no man's land between two border gates, then detonated it remotely about 20 minutes later.
