Ali Salman, the head of the Islamic National Accord Association, the main Shia political formation, called for Sunni-Shia harmony, following the sectarian clashes a day earlier. Six opposition groups officially submitted their demands to the government, conditions that include the abolition of the 2002 constitution and "the election of a constitutional assembly for drafting a new basic law" for the country. 6–15 March On 6 March, thousands of protesters gathered outside the prime minister's office in Bahrain to demand that he step down, while a government meeting was in progress there. In addition, demonstrators remained in hundreds of tents at Manama's Pearl Roundabout. On 8 March, three Shiite groups (Haq Movement, Wafa, and the Bahrain Freedom Movement) formed the "Coalition for a Bahraini Republic" and called for the abolishing of the monarchy and the establishing of a democratic republic. On 9 March, in a protest that began at the Ras Roman mosque, thousands of Shia Bahrainis marched on the immigration office in the capital, Manama, and voiced their opposition towards the granting of citizenship to Sunnis from other countries serving in the country's military. However, in order to emphasise that the protest was against the government's naturalisation policy, and not against Bahrain's native Sunni population, participants also shouted slogans about Sunni-Shia unity. On 10 March, at a school in Saar, clashes erupted between naturalised Sunni parents – mainly from Syria and Pakistan – and Shia parents, after some Shia pupils launched anti-government protests. In a separate incident, teachers, students and their parents took part in a protest in front of the ministry of education, in Isa Town, demanding the resignation of Dr Majid bin Ali al-Naimi, the education minister. On 13 March, riot police used tear gas and rubber bullets in an attempt to force a group of hundreds of anti-government protesters from blocking the capital's financial district, where demonstrators have been camped out for more than a week. A video that appeared on YouTube showed one protester being shot with a tear-gas canister at close range. Riot police also encircled demonstrators at Pearl Roundabout, the focal point of protests in Bahrain for nearly a month, firing tear gas canisters, while other protesters staged a number of marches on symbolic targets – the prime minister's office, the foreign ministry, and the state television building, among others.
