In Bahrain, clashes erupted after the imposition of three-month state of emergency to quell political unrest. Saudi-led GCC military force arrived in Bahrain yesterday to help the rulers. Unconfirmed reports quoting medical sources said that more than 200 people were injured in clashes in a Shiite village south of the Bahraini capital. The United States warned that there is no military solution to the political upheaval in Bahrain and that any violence against peacefully expressed political demands should be stopped. In Yemen, reports say that anti-government tribesmen in the north stormed a security building and shot dead four soldiers in a revenge attack after government troops opened fire on protesters.
