U.N. rights boss doubts legality of Israel's Gaza offensive

GENEVA (Reuters) - The United Nations human rights chief on Friday voiced serious doubts that Israeli's military operation against Gaza complied with international law banning the targeting of civilians, and called on both sides to respect the rules of war.

International law requires Israel to take all measures to ensure that its attacks are proportional, distinguish between military and civilian objects, and avoid civilian casualties, U.N. High Commissioner for Human Rights Navi Pillay said.
