An international group of five peace activists got far inside the Büchel Air Base in Büchel, Germany, after nightfall on Monday, July 17, 2017, and for the first time in a 21-year-long series of protests against the deployment of U.S. B61 thermonuclear bombs there, climbed on top of one large bunker used for nuclear weapons. After cutting through two exterior fences and two more fences surrounding the large earth-covered bunkers, the five spent more than one hour unnoticed sitting on the bunker. No notice of the group was taken until after two of them climbed down to write “DISARM” on the bunker’s metal front door, setting off an alarm. Surrounded by vehicles and guards searching on foot with flashlights, the five eventually alerted guards to their presence by singing, causing the guards to look up. The internationals were eventually taken into custody more than two hours after entering the base.
