I said something really insensitive to my boyfriend and he won’t speak to me?

So his sister is going travelling for a few months on her own and I stupidly said oh its not safe she’ll need to be careful on her own. I also said the country she’s visiting lots of people have been killed there and he got angry and said don’t say stuff like that when I’m already worried. I didn’t mean she’s going to get killed, I just meant in general. Now he won’t talk to me at all and is super angry. What do I do? :(
