"I think the UN is right to speak out in the way that it has, because international law is very clear that there must not be the targeting of civilians or the targeting of schools if that is what has happened. The UN as the international body is right to speak out in the way it has."

"The UN has spoken very clearly and I think they are right to speak very clearly... I'm not an international lawyer, so that's up to international lawyers. But international law is very, very clear that the use of force always has to be proportionate and civilians should not be targeted."
"We obviously do think it is appalling the loss of life that there has been. From the start, though, we have also made the point that if the Hamas rocket attacks on Israel stop then that would be probably the fastest way to stop this conflict."
