A South Korean military official said Friday, Nov. 3, 2017, the B-1B bombers based in Guam were escorted by two South Korean F-16 fighter jets during the drills Thursday at a field near the South's eastern coast. The drills simulated attacks on land targets, but didn't involve live weapons, said the official, who did not want to be named, citing office rules. (South Korean Defense Ministry via AP, File)
