at achieving greater political freedom and respect for human rights; they were not intended to directly threaten the monarchy. Lingering frustration among the Shiite majority with being ruled by the Sunni government was a major root cause, but the protests in Tunisia and Egypt are cited as the inspiration for the demonstrations. The protests were largely peaceful until a pre-dawn raid by police on 17 February to clear protestors from Pearl Roundabout in Manama, in which police killed four protesters. Following the raid, some protesters began to expand their aims to a call for the end of the monarchy. On 18 February army forces opened fire on protesters when they tried to reenter the roundabout, fatally wounding one. The following day protesters reoccupied Pearl Roundabout after the government ordered troops and police to withdraw. Subsequent days saw large demonstrations; on 21 February a pro-government Gathering of National Unity drew tens of thousands, whilst on 22 February the number of protestors at the Pearl Roundabout peaked at over 150,000 after more than 100,000 protesters marched there. On 14 March, Saudi-led GCC forces were requested by the government and entered the country, which the opposition called an "occupation". King Hamad bin Isa Al Khalifa declared a three-month state of emergency on 15 March and asked the military to reassert its control as clashes spread across the country. On 16 March, armed soldiers and riot police cleared the protesters' camp in the Pearl Roundabout, in which 3 policemen and 3 protesters were reportedly killed. Later, on 18 March, the government tore down Pearl Roundabout monument. After the lifting of emergency law on 1 June, several large rallies were staged by the opposition parties. Smaller-scale protests and clashes outside of the capital have continued to occur almost daily. On 9 March 2012 over 100,000 protested in what the opposition called "the biggest march in our history". The police response has been described as a "brutal" crackdown on "peaceful and unarmed" protestors, including doctors and bloggers. The police carried out midnight house raids in Shia neighbourhoods, beatings at checkpoints, and denial of medical care in a "campaign of intimidation". More than 2,929 people have been arrested, and at least five people died from torture while in police custody. On 23 November 2011 the Bahrain Independent Commission of Inquiry released its report on its investigation of the events, finding that the government had systematically tortured prisoners
