The U.N.'s public health agency says it has trained 90 Iraqi medics in "mass casualty management" as part of its preparations for the Mosul offensive, with a special focus on responding to chemical attacks. The United Nations' refugee agency is shipping tents, blankets and other aid from the United Arab Emirates to northern Iraq to help those affected by the military campaign to retake Mosul from the Islamic State group. Soliman Mohamed Daud, a senior UNHCR supply officer, told The Associated Press that 7,000 units of the relief aid will be sent to northern Iraq.
