In a fresh effort to broker a truce, U.N. chief Ban Ki-moon was to leave Saturday for the Middle East to help mediate the Gaza conflict.

Israeli officials have said the offensive could last up to two weeks. The military reported making steady progress but said dozens of tunnels remain and would not give a time frame for its operation.
