Bahrain's ruling monarchy, no longer able to contain growing protests, has called in for help from Saudi Arabia. An adviser to the Khalifa family, Nabeel al-Hamer said, "Forces from the Gulf Cooperation Council have arrived in Bahrain to maintain order and security." According to AFP, 1,000 troops from Saudi Arabia's Gulf Peninsula Shield Force entered Bahrain yesterday. This could get ugly.
