"War of the Worlds" foes (8)

I believe the answer is:

martians

(Other definitions for martians that I've seen before include "Sci-fi aliens from the war planet" , "Little green men?" , "Aliens from the Red Planet, common in sci-fi" , "Extraterrestrial beings" , "War of the Worlds invaders" .)

I've seen this clue in the Newsday.
