Syria remains completely offline since Friday, June 3 morning, the country's state telephone and internet service said.
"We have a problem. We are now striving to tackle it," a spokeswoman for the internet service said without giving further details, RIA Novosti reported.
Pro-democracy protests have been breaking out in Syria each Friday (which is the country's official holiday) over the last two and a half months. The first protesters demanding President Bashar Assad resignation and more democratic freedoms were spotted in the city of Deraa in mid-March and soon pro-opposition campaigns spread to other Syrian regions.
Activists organize the rallies through Facebook and Twitter. Syria has several times severed its connections to the internet in most rebellious territories in a bid to hamper the protests, but this is the first time the entire internet services in Syria have been down.
Over 1,000 people have been killed since the beginning of the unrest in the country, Syrian rights activists claim.
