'Brutal attacks' alleged in Bahrain

The king of Bahrain has declared a state of emergency across the country for three months. Local police are now being backed up by 1,000 Saudi troops, who entered the country on Monday following weeks of political unrest.

Among those wounded in violent protests are undercover police found in the Shia areas of Bahrain, where hospital staffers are overwhelmed by the influx of the injured.
