Bahrain has ordered the release of two former MPs arrested in May after a crackdown on Shiite-led protests pending their trial in a civilian court, state new agency BNA said on Sunday. The public prosecutor has decided to "release several detainees ... until the (civilian) court looks into their cases," including "two former MPs and a lawyer," BNA reported. The two former MPs from Bahrain's largest Shiite formation, the Islamic National Accord Association (Al-Wefaq), Matar Matar and Jawad Fayrouz, were arrested at gunpoint in early May. The men were being tried by a national safety court for having allegedly called for regime change and spreading rumours linked to the pro-democracy protests. Bahrain had declared a State of National Safety, a lower degree of emergency, on March 16, a day before security forces crushed month-long street protests demanding democratic reforms. On June 1, King Hamad announced a lifting of the state of emergency and all cases were referred to civilian courts. At least 500 people have been detained in Bahrain since the protests broke out in the Sunni-ruled Gulf kingdom which has a Shiite majority, according to Amnesty International. Almost 2,000 people have been dismissed or suspended from their jobs, it said. Security forces in the archipelago cracked down on the mostly Shiite protesters in mid-March after being backed by troops with tanks who rolled in from neighbouring Sunni Gulf monarchies. Bahraini authorities said 24 people were killed during the unrest, most of them demonstrators.
