By Stephanie Nebehay GENEVA (Reuters) - The top U.N. human rights official said on Thursday she believed Israel was deliberately defying international law in its military offensive in Gaza and that world powers should hold it accountable for possible war crimes. Israel has attacked homes, schools, hospitals, Gaza's only power plant and U.N. premises in apparent violation of the Geneva Conventions, according to Navi Pillay, U.N. High Commissioner for Human Rights. "Therefore I would say that they appear to be defying... deliberate defiance of obligations that international law imposes on Israel," Pillay told a news briefing.
By Nidal al-Mughrabi and Jeffrey Heller GAZA/JERUSALEM (Reuters) - Israeli Prime Minister Benjamin Netanyahu, facing international alarm over a rising civilian death toll in Gaza, said on Thursday he would not accept any ceasefire that stopped Israel completing the destruction of militants' infiltration tunnels. The Israeli military estimated on Wednesday that accomplishing that task, already into its fourth week, would take several more days. "I wont agree to any proposal that will not enable the Israeli military to finish this important task, for the sake of Israel's security." Leaving open the option of widening a ground campaign in the Hamas Islamist-dominated Gaza Strip, the Israeli military said it had called up an additional 16,000 reservists. Gaza health officials said 19 Palestinians were killed in Israeli assaults on Thursday, which included an air strike on a van in the heart of Gaza City, which killed two people.
