Israel's foreign minister said on Tuesday that United Nations Secretary-General Antonio Guterres was not fit to head the global body, saying he had not done enough to condemn militant group Hamas and was too close to Iran. His comments, made at a press conference inside the UN building in Geneva, represent an intensification of Israel's criticism of the UN in the same week that the latter mourned the killing of more than 100 of its staff in Gaza. "Guterres does not deserve to be the head of the United Nations," Israeli Foreign Minister Eli Cohen said.
