From the Beeb. UK Armed Forces minister Nick Harvey said it was unclear how long the mission would take, adding that using ground troops "could not be ruled out".

He told the BBC: "We don't know how long this is going to go on for, we don't know for example... whether this might arrive at a state of stalemate or whether in a sense it will be possible to degrade his military capability relatively fast.

"Ask me again in a week, perhaps we'll have a clearer picture of what sort of scale of campaign we're in for."

What resolution was it, then? Remind me...
