Alien Attacks?

i wonder if there are any reports of aliens / ufos attacking people or reports of people being injured or killed by them.

i saw the movie night skies i think it has to do with the Phoenix Lights, and in the end of the movie it states that 3 or 4 people went missing or got killed by the aliens and one of the abductees showed up very from where he was abducted. I know it's a movie but it could have some truth in it.

thanks
