KABUL, Afghanistan — American and Afghan military personnel were fired on while conducting an operation in Afghanistan’s eastern Nangarhar province, the U.S. military said Saturday, and one official said there were U.S. casualties.

Several U.S. personnel were either injured or killed, but the exact number and other details were not provided, said the U.S. official, who agreed to discuss the incident only on condition of anonymity.


A U.S. military spokesman, Col. Sonny Leggett, said in a statement that both Afghan and U.S. personnel were “engaged by direct firing.”
