During the initial attack and takeover of the buildings, a journalist and a police officer were killed, and three others, including a city councilor, were injured. After a 39-hour standoff, the gunmen surrendered and all remaining hostages were released.
“The gunmen were led by Hamaas Abdul Khaalis, who wanted to bring attention to the murder of his family in 1973.

“The siege is mentioned in Joni Mitchell’s song ‘Otis and Marlena’ from her 1977 album ‘Don Juan’s Reckless Daughter.’ In the song, the title characters travel ‘for sun and fun / While Muslims stick up Washington’.”
