When government forces tried to disperse an improvised roadblock set up by rebels near Sanaa University, the insurgents returned fire and battled the government troops for an hour, forcing them to retreat. That’s the kind of democratic opposition Obama praised days ago.
Saudi Arabia and the GCC states offered to mediate a transfer of power from Yemen’s president to the rebels. That means that Saudi Arabia is no longer backing the president, as it did for two months, and only needs assurances from the opposition that Yemen won’t fell under the spell of Iran. Presumably an Al Qaeda presence in Yemen would be okay.
