Warplanes hover over Manama brutalizing anti-regime protests in the Bahraini capital of Manama, amid heavy military presence.

Military forces have been deployed in Manama over fears of anti-government protests as the opposition in the tiny Persian Gulf state has pledged to rise again in another "Day of Rage."

Bahraini opposition activists announced plans for the Friday protests in defiance of a martial law imposed since last week.

Nine demonstrations -- whose plans were circulated by email and internet -- are arranged to be held across crisis-hit Bahrain on March 25.

One of the rallies is expected to be heading toward the airport and another aims for Manama's Salmaniya hospital.

Government crackdown on peaceful demonstrations in Bahrain has recently been aided by troops from Saudi Arabia.

Meanwhile, reports said that the Saudi forces have forcefully taken about 100 people out of the hospital and shot them dead.
