Hague, on his way to Qatar Summit in April 2011, called for intensified sanctions on the Libyan régime and for a clear statement that Gaddafi must go: "we have sent more ground strike aircraft in order to protect civilians. We do look to other countries to do the same, if necessary, over time". "We would like a continued increase in our (NATO's) capability to protect civilians in Libya", he added. Whether NATO ratcheted up operations depended on what happened on the ground, Hague said. "These air strikes are a response to movements of, or attacks from, régime forces so what happens will be dependent on that", he said. Whether the Americans could again be asked to step up their role would also "depend on the circumstances", he added.
