Carney says 4 service members killed and dozens injured in fire at Alberta military base

What the coverage shows

All three outlets frame the story around a serious fire at a Canadian military base in Alberta with people killed or injured, and all note that officials have not said what caused it. BBC News is the most cautious, saying several people were killed or injured, while NBC News says several were killed and many others were rushed to hospitals. Reuters mentions the fire only in a brief item alongside its France protests lead, making this the least developed treatment of the event.
