Reports are still coming in piece-meal, but based on what is known, massive demonstrations were met with force by the regime. The death toll is somewhere between 8 and 15 (even official reports contradict each other).

Here's the version from the New York Times late Sunday (North American times).
Further reports with more details should begin to be seen as today progresses.
