(AP) -- Social networking site LinkedIn is once again accessible in China, after apparently being blocked by authorities following online calls for Middle East-style protests across the country.
The unidentified organizers of the protests have urged citizens to rally Sunday in cities across China. Last weekend, an initial attempt to organize protests attracted only a handful of active participants, though it unnerved the authoritarian government.
Beijing has responded by increasing Internet filtering, stepping up police presence and detaining dissidents.
LinkedIn could not be opened in China for a few days this week but was working again Saturday. The Mountain View, California, company has said it was monitoring the situation.
