BEIRUT Internet and telephone service were restored across much of Syria on Saturday following a two-day, nationwide communications blackout that came during some of the worst fighting to hit the capital since July.
Experts say the shutdown was likely caused by President Bashar Assad's regime, raising fears that the government is taking increasingly bold measures to cut off the country from the outside world as it tries to crush a relentless rebellion.
Renesys, a U.S.-based network monitoring firm that studies Internet disruptions, said in a statement Saturday that service went back up around 4:32 p.m. local time in Syria, describing it as a "largely complete restoration of the Syrian Internet."
Mobile telephone networks also appeared to be mostly back up Saturday. A Britain-based activist group, the Syrian Observatory for Human Rights, said it was receiving dispatches from many parts of the country. Many land lines had remained in working order.
The SANA state news agency said technical teams brought both Internet and telephone services back online Saturday in Damascus and its suburbs the flashpoints of recent fighting between government soldiers and rebels.
The communications blackout began Thursday, raising fears of a burst of fighting outside the public eye. The government and rebels have blamed each other for cutting the lines.
Syrian rebels are fighting a 20-month-old revolt against the Assad regime. Activists say some 40,000 people have been killed in the crisis, which began with pro-democracy protests but has morphed into a civil war.
On Saturday, Syrian troops backed by helicopter gunships clashed with rebels as government forces pushed a major offensive on villages and towns near the capital's international airport, activists said.
SANA reported a car bomb exploded in the Damascus neighborhood of Ish Alwarwar. There was no immediate word on casualties.
The fighting over the past few weeks in Damascus is the most serious the capital has seen since July, when rebels captured several neighborhoods before a swift government counteroffensive swept out the opposition fighters.
Activists said forces loyal to Assad were battling rebels in towns just south of the capital, including Aqraba, Beit Saham and Yalda near the airport. The Observatory said many were feared killed in government shelling of Beit Saham.
Syrian state TV said troops were battling fighters from the al Qaeda-inspired Jabhat al-Nusra group in areas around the airport and that many of the rebels were killed, including two Iraqi citizens.
