"According to unofficial reports, the United States stores approximately 50 B61 nuclear bombs at Incirlik Air Force Base in southern Turkey. After the failed coup in Turkey in mid-July 2016, the government arrested several high-ranking officers from the base and cut power for nearly a week. In late July, Turkish citizens protested outside the base, calling for its closure, though Turkish officials have assured U.S. officials that the United States will retain access to Incirlik and other bases in Turkey. These events have sparked debate about the weapons' security and plans to continue storing them at Incirlik."
