(Adnkronos) – The agents guarding the CIA headquarters in Langley opened fire in what is being called a “security incident” in which one person was non-fatally injured. NBC reports, citing sources informed of the incident that occurred a few hours after the attack in which the two Israeli diplomats, Yaron Lischinsky and Sarah Milgrim, were killed in front of the Jewish Museum in Washington. There are no indications that these two incidents are related, the broadcaster adds.
