"A new report charges that Bahrain has badly injured and even killed protesters by swamping them with massive clouds of tear gas, flooding closed spaces such as cars and houses with the toxic chemicals. Physicians for Human Rights, a rights group based in Massachusetts, said the island nation was misusing tear gas against Shiite Muslim civilians, wielding it as a weapon with grave health risks. The unrelenting gas attacks cause such severe suffering that they amount to torture, the group said. Two men, one of them asthmatic, died after repeatedly being exposed to tear gas in their homes, the report found. Several women suffered miscarriages shortly after being exposed to the gas, the group said. Other Bahrainis reported vomiting, shortness of breath, even loss of consciousness from the gas that has blanketed villages outside the capital."
