No, they didn't mean that, because I listened to the youtube video and the lady quite definitely says 'is being killed', which is of course as correct as 'is killed'. The only difference between the two in my opinion is that the progressive emphasises the 'on-going' aspect. The meaning is otherwise the same."Has been" says this was the rate of killings up until now (but it may be different from now on). That is probably not what they mean.
