U.N. Secretary-General Ban Ki-moon chided world leaders today for not doing enough to halt what he called an unacceptable level of violence in Gaza and press for a long-term political solution, according to Reuters. In his third statement in three days on Gaza, where Israeli air strikes aimed at stopping Hamas rocket fire on southern Israel have killed more than 325 Palestinians, Ban again called for an immediate ceasefire by both sides. Two Israelis have been killed. "I think regional and international partners have not done enough. They should do more," Ban told a news conference. "They should use all possible means to end the violence and encourage political dialogue, emphasizing peaceful ways of resolving differences." "I urge them to act swiftly and decisively to bring an early end to this impasse," Ban said. "At the same time, other world leaders must also step up efforts to support a longer term resolution of the issue."
