The title of a story on NHK News Web Easy is
Which, with my abilities, translates as
Bus accident. As speed increased it kept running?
I don't understand why that か is there at the end of the sentence though. Is the title of the story actually a question? Or does this signify something else? Frankly I'm not even sure my translation is correct. It seems an odd thing to say, since a speed increase would seem to imply that of course the bus kept running. If the bus wasn't running, the speed would go down, generally speaking.
