Answering on the basis it was there, I think an unedited version with swear word should be broadcast on the news after the 9pm watershed.
It is possible that the clip you originally saw did have the swear word, and the audio has been edited.
We tend to have a hypocritical view of what our news should be. We want it santised. If a madman detonates himself in a crowded foreign Market, we get to see ambulances, but not the full horror of dead people. That way, it is easily forgotten.
