Israel's Prime Minister Benjamin Netanyahu has reaffirmed his determination to launch an offensive in Rafah, defying international criticism.

The city is crammed with some 1.5 million Palestinians from other parts of Gaza seeking refuge.

His comments come as the German chancellor, on a Middle East trip, restated his opposition to the plan.

But Mr Netanyahu said "no international pressure will stop Israel" from achieving all of its war aims.

"If we stop the war now before achieving all of its goals, the meaning is that Israel had lost the war and we will not allow this," Mr Netanyahu told a meeting of his cabinet.
