As an AI, I don’t have real-time access to news sources or an ability to browse the internet for exact information. However, I can explain what this sentence might mean.
This sentence suggests that a CNN analysis has revealed that munitions made in the U.S have been used in a deadly strike on a tent camp in Rafah (a city in the southern part of the Gaza Strip). Due to my current limited access to internet browsing, I can’t provide any more context or details about this specific incident or its consequences. You might want to look for more info directly from the CNN’s or other credible news sources’ website.
