Organ banks around the country have noted an increasing number of organs from donors who have died of overdoses.
The Pentagon says two U.S. fighter jets dropped bombs on Islamic militants in Iraq towing artillery outside Irbil near U.S. personnel.
Pentagon press secretary Rear Adm. John Kirby says two F/A-18 jets dropped 500-pound bombs on a piece of artillery and the truck towing it.
President Barack Obama authorized such airstrikes Thursday when the Islamic state militant group advanced on Irbil, in northeastern Iraq, where U.S. military trainers are stationed.
Defense Secretary Chuck Hagel says the U.S. military has enough intelligence to clearly single out Islamic militants and launch effective airstrikes if they threaten U.S. interests or the thousands of refugees who fled to a mountaintop.
Hagel also says that more than 60 of 72 bundles of food and water airdropped onto the mountain reached the Iraqi religious minorities stranded there.
