BEIRUT — Syrian rebels captured a helicopter base just outside Damascus Sunday in what an activist called a “blow to the morale of the regime” near President Bashar Assad's seat of power.
The takeover claim showed how rebels are advancing in the area of the capital, though they are badly outgunned, making inroads where Assad's power was once unchallenged. Rebels have also been able to fire mortar rounds into Damascus recently.
The director of the Britain-based Syrian Observatory for Human Rights, Rami Abdul-Rahman, said rebels seized control of the Marj al-Sultan base on the outskirts of Damascus on Sunday morning. He said at least 15 rebels and eight soldiers were killed in the fighting that started a day earlier. The rebels later withdrew from the base.
Rebels appear to be trying to take over air bases and destroy aircraft in order to prevent the regime from using them in attacks against opposition forces around the country.
The rebels have no protection against the attack helicopters and fighter jets that have been blasting their positions.
Rebels have been attacking air bases in different parts of Syria, mostly in the northern regions of Idlib and Aleppo.
In the battle at the base outside Damascus, Abdul-Rahman and Damascus-based activist Maath al-Shami said rebels destroyed two helicopters with rocket propelled grenades and captured a tank. They say the base, which is on the eastern outskirts of Damascus, houses several radar positions.
“This is a blow to the morale of the regime, because it is close to the heart of the capital,” said Abdul-Rahman, referring to the base that is about 15 kilometers (10 miles) from Damascus.
Al-Shami said the rebels withdrew from the base after they captured some ammunition. He said they feared counterstrikes by regime aircraft.
An amateur video posted online showed rebels walking next to two destroyed helicopters. At least three other helicopters appeared undamaged. Black smoke billowed in the distance.
Another video showed several radar posts on hills inside the large compound. Parked military trucks stood inside as rebels roamed freely.
The activist videos appeared genuine and corresponded to other AP reporting about the events depicted. Syria restricts the access of reporters.
The Observatory also reported violence in other parts of Syria, including the country's largest city of Aleppo in the north and the capital itself.
It said rebels on Sunday captured a training base for the Popular Front for the Liberation of Palestine-General Command near the Damascus suburb of Douma. The PFLP-GC is one of the Palestinian factions most loyal to Assad.
The PFLP-GC said in a statement late Saturday that the base was under attack. It said that thousands of activists and fighters who fought against Israel were trained at the base over the past 30 years.
Also Sunday, the Observatory said a bomb targeted a bus in the southern village of Othman, killing at least five people and wounding dozens. It said rebels and troops clashed in the southern region of Quneitra on the edge of the Israeli-occupied Golan Heights.
The Local Coordination Committees, another activist group, said residents found 12 bodies in the Damascus suburb of Daraya, scene of heavy clashes between rebels and government troops over the past few days.
State TV said troops clashed with al-Qaida militants in Daraya, killing some of them and confiscating a mortar that they were using in their attacks.
The station said that troops killed an al-Qaida affiliated Palestinian militant known as Abu Suhaib in the Damascus suburb of Hajira. It said his group was behind several bombings in Syria that killed and wounded dozens of people.
Assad's regime blames the revolt on a foreign conspiracy. It accuses Saudi Arabia and Qatar, along with the United States, other Western countries and Turkey, of funding, training and arming the rebels, whom it calls terrorists.
Syria's conflict erupted in March 2011 with an uprising against President Bashar Assad's regime, inspired by other Arab Spring revolts. It quickly morphed into a civil war that has since killed more than 40,000 people, according to activists.
