Israel's prime minister has said 'if we had wanted to commit genocide, it would have taken exactly one afternoon' amid growing war of words over starvation in Gaza.

In a press conference, he rebutted accusations of deliberately starving civilians.

Netanyahu has consistently denied claims that his forces are committing genocide in the Strip and has said that Israel tries to avoid civilians who are put in harm's way by Hamas.

The remarks came during press conferences in Jerusalem as he defended his government's latest military push into Gaza City.

The planned offensive, he said, is aimed at defeating Hamas, but it has drawn condemnation from some of Israel's closest allies and the United Nations, who say it 'will likely trigger another calamity in Gaza'.
