President Barack Obama ordered about 350 more US troops to Baghdad to protect American diplomatic facilities and staff in the Iraqi capital, the White House said. The Sunni extremist group has declared an Islamic "caliphate" in regions under its control in Iraq and Syria, after it swept through much of the Sunni Arab heartland north of Baghdad and then stormed minority Christian and Yazidi areas. The US has been carrying out air strikes on IS positions in Iraq and already has hundreds of personnel shoring up diplomatic security in Iraq. "The president authorized the Department of Defense to fulfill a Department of State request for approximately 350 additional US military personnel to protect our diplomatic facilities and personnel in Baghdad, Iraq," a White House statement said.
"These smoky, dirty fuels are often used in an open fire or simple stove, resulting in high levels of household air pollution in poorly ventilated homes," said a statement, released Wednesday. Led by Stephen Gordon of the Liverpool School of Tropical Medicine and William Martin of Ohio State University, the team concluded that 600-800 million families worldwide are at higher risk of respiratory tract infections, pneumonia, asthma, lung cancer and other ailments as a result of the air they breathe at home. Studies in India have found that household air pollution can be three times higher than on a typical London Street, and well above the World Health Organization's recommended safety levels. "Estimates suggest that household air pollution killed 3.5 to four million people in 2010," wrote the team.
