Saudi troops arrive in Bahrain as protests escalate

``Saudi forces have reportedly arrived in Bahrain to reinforce its police, who clashed with protesters yesterday in an escalation of the month-long Shiite-led protests calling for democratic reform... Opposition groups said Monday that the Saudi intervention was a declaration of war. Protests that began with calls for democratic reform and an end to Shiite discrimination are now calling for regime change... Meanwhile, a pro-government parliamentary bloc on Monday called on the king to impose martial law after 100 people were reportedly wounded Sunday. Police attacked the mostly Shiite protesters who were blocking a highway leading to the financial district in the capital Manama. They used tear gas and rubber bullets against the demonstrators, but were unable to disperse them.''
