Tear gas
In incidents on 18 April, 21 May and 15 December, tear gas grenades were fired at Rajab's house in the village of Bani Jamra by unknown assailants. In the first incident, HRW identified the grenades thrown into the Rajab family's compound as US-manufactured munitions to which only Bahrain's security forces would have had access. Tear gas penetrated into the adjacent home of Rajab's 78-year-old mother who suffers from respiratory disease, causing her great distress. On 21 May, four gas grenades were fired at the house. This time, according to Rajab, the grenades were smaller than those used in the mid-April assault and there were no marks identifying the manufacturer.
