Four gas grenades were fired at the house at 3:30 am Saturday in the village of Bani Jamra, Bahrain, and two broke through the windows in quarters occupied by his brother, Nader, and his family. Human Rights Watch noted that the grenades were manufactured in the United States and were of a type to which only the Bahrain Defense Authorities had access. Now it appears the Bahraini government has found a new supplier. Rajab said: "This time, the grenades were of a smaller dimension than in mid-April, and there were no markings of manufacture."
