Hello. I'll be grateful for your help.

Question

Which word is it better to use to complete the following sentence: "Only two people died in the fire but there were a lot of 1)victims; 2)casualties"?
The two words look like synonyms to me(I consulted a dictionary), but maybe they are used differently. And is it possible to use the word "injured", ie "... a lot of injured", maybe "a lot of the injured"?
Thank you for all your time and advice.

Answer 1

I'd word it:

Two people died in the fire, but there were a lot of other casualties.

Two people died in the fire, but there were a many injured people.
