Chinese nationals fired lasers near a military base in east Africa against U.S. military aircraft in the region, injuring several pilots.
Pentagon Press Secretary Dana White said the U.S. government made diplomatic protests to the Chinese government over several recent incidents of laser firings near China's first overseas military base at Djibouti.
"These are very serious incidents. There have been two minor injuries. This activity poses a threat to our airmen," White told reporters.
"We have formally demarched the Chinese government, and we've requested that the Chinese investigate these incidents," she added.
