BEIRUT — Syria's rebels stepped up attacks on strategic sites including a sprawling military complex in the country's north on Friday, while reports emerged that President Bashar Assad's forces continued to fire Scud missiles at rebel areas.
Russian President Vladimir Putin told European leaders that Russia does not seek to protect Assad but that only a negotiated solution can end the conflict — an outcome that looks unlikely as rebels make gains across the country.
While few observers expect Syria's 21-month-old conflict to end soon, most say steady rebel advances appear to be tipping the balance in favor of those fighting to topple Assad's regime.
Anti-regime activists reported rebel attacks on strategic government sites in northern Syria on Friday, showing rebel efforts to cut government supply lines, free up roads and seize arms from government bases.
Near the northern city of Aleppo, rebels clashed with government forces at a sprawling military complex by the town of Al-Safira, activists said.
An activist in the town said the complex contains military factories, a scientific research center that produces chemical weapons as well as an air defense and an artillery base.
Rebels seized the artillery base earlier this week and have been trying to seize the air defense base, said Hussein, who gave only his first name for fear of retribution.
The town's proximity to the facilities has cost it dearly, he said. Government airstrikes often target civilian areas, and more than two-thirds of the town's residents have fled, fearing the regime will use chemical weapons.
"We are scared that they will be blown up or that the regime will use them in revenge on the town," he added.
Bilal Saab, head of the Institute for Near East and Gulf Military Analysis, confirmed that the Al-Safira complex houses a chemical weapons production facility but said it is unclear if such weapons have been stored there ready for use, or if rebels would even be able to use such weapons.
The Britain-based Syrian Observatory for Human Rights said seven rebels were killed in clashes in the area on Friday. It said nearly two dozen more died in a government airstrike earlier this week after they captured a military warehouse.
Activists also said rebels had launched attacks on a number of military targets near the central city of Hama.
Activist Mousab Alhamadee said rebels had seized five army posts in the last two days near the town of Morek, which straddles the country's primary north-south highway north of Hama. Only one army tank battalion remains in the town's immediate area, he said, giving the area's rebels much more freedom to move.
"The regime is losing a complete geographic area," he said.
Syria's conflict started with political protests in March 2011 and has since evolved into a full-scale civil war, with rebel brigades across the country fighting Assad's troops.
The government says the rebels are terrorists backed by foreign powers that seek to destroy the country. It does not give death tolls, although anti-regime activists say more than 40,000 have been killed.
International diplomacy has failed to slow the conflict.
On Friday, Russian President Vladimir Putin said that his country does not seek to preserve Assad's rule but wants a "democratic regime in Syria based on the expression of people's will" — an outcome he said can only come through negotiations.
"We aren't a defender of the current Syrian leadership," Putin told European leaders in Brussels.
Throughout the conflict, Russia has been one of Assad's greatest backers, selling him arms and, along with China, protecting Syria from censure by the U.N. Security Council.
But Russian officials have recently distanced themselves from Assad's regime, suggesting they are resigned to his potential ouster.
Also Friday, NATO's top official said that Syria has continued to target rebel areas with Scud-type missiles.
Secretary-General Anders Fogh Rasmusen called the attacks "acts of a desperate regime approaching collapse."
U.S. and NATO officials first reported Syria's use of Scud missiles one week ago, prompting a swift denial from the Syrian government.
NATO agreed earlier this month to deploy Patriot anti-missile systems along Syria's northern border with Turkey — a move Fogh Rasmussen said was justified by the new attacks.
One of the Scuds apparently hit the rebel town of Marea, near Aleppo.
An activist in the town who goes by the name Abu al-Hassan said Friday he was awoken the day before by the largest explosion he'd ever heard in the town, a frequent target of regime airstrikes.
"It shook the house and my kids came running in saying, 'Daddy, daddy!'" he said. "They were terrified."
Al-Hassan said the missile fell in a field, causing no casualties.
Videos purporting to show the impact site showed a crater some six meters (yards) deep in a green field. They appeared genuine and corresponded with other AP reporting on the incident.Comment on this story
Also Friday, a prominent news anchor from Syrian state TV said he had defected after being repeatedly interrogated by the country's intelligence services.
Speaking from an undisclosed location outside of Syria, Ahmad Fakhouri told Al-Arabiya TV that he'd fled the country eight months ago with rebel help.
"I look forward for the day when Syria will be free and I can return to my country to do my job," he said.
Syrian TV's head office in Damascus told The Associated Press that Fakhouri had left the station to work for state-run radio.
An official at the radio station said Fakhouri was on vacation.
