Israeli Foreign Minister Tzipi Livni has said that the attack against Hamas is an expression of self defence by her country and would not end till the time the Hamas realises that it has to stop all terrorist activities against Israelis.

"Until a moment in which we have Hamas weaker, in which we know that they understand that Israel is not willing to live in realities in which our citizens are being targeted, and this is a combination between the military ability and the motivation, and we are working on both sides," Livni said in an interview when asked how long the war against Hamas would continue.

She also said that there can't be a truce or ceasefire between Israel and Hamas, simply because one is country and other is a terrorist organization.

"There is one thing that frustrates me. The idea of saying something like, Israel and Hamas need to stop. A ceasefire between Israel and Hamas, it's not the same. I'm not willing to put Israel and Hamas in the same package or even use the same wording, because, as you said before, we are expressing our right of self defence," said the Israeli Foreign Minister.

"Israel is a state which is a member of the international community, while Hamas is a terrorist organization. Israel acts against Hamas because it targets Israel. So they know what to do in order to stop it," Livni said.
