BEIRUT — Syrian rebels launched a coordinated assault on the main prison in the northern city of Aleppo Wednesday in an attempt to free hundreds of regime opponents believed to be held in the facility, activists said, while an Internet blackout engulfed the country for the second time in two weeks.
The Britain-based Syrian Observatory for Human Rights said rebels detonated two car bombs simultaneously outside the walls of the central prison Wednesday morning before trying to storm the facility.
Fierce clashes are taking place between President Bashar al-Assad's troops and opposition fighters around the detention center, according to Observatory director Rami Abdul-Rahman.
He added that Aleppo's central prison is believed to be holding about 4,000 prisoners, around 250 of whom are jailed for reasons related to the 26-month-old uprising against Assad's regime.
There were no immediate reports of casualties.
Syrian residents and the the U.S.-based Renesys Corp. said Syria's Internet went offline Wednesday morning at 10:00 a.m. local time.
"It looks like a replay of what happened on the seventh and eighth," Renesys chief technology officer James Cowie said by telephone, referring to last week's nationwide outage. He said the cause was not immediately clear.
"It's entirely consistent with a technical fault at a central facility; it's also completely consistent with a decision to use an Internet kill switch," he said.
Preliminary data from Google Inc.'s Transparency Report website also pointed to a nationwide blackout, with Syria's online traffic share nose-diving to 0 percent on Wednesday morning.
Syrian government websites, including the SANA state news agency, appeared to be down as well, but SANA reported on its twitter account a technical problem. It said maintenance units were working to restore the Internet as soon as possible. It did not elaborate.
An official at the Syrian communications department said an Internet cable was cut in a Damascus suburb and said it will take up to four hours to fix. The official spoke on condition of anonymity because he was not authorized to give official statements. He did not say what caused the cut.
Syrian authorities have cut phone and Internet service in select areas in the past to disrupt rebel communications when regime forces were conducting major operations.
Such widespread outages, however, have been rare. The reason for the May 7 outage is still unclear.
