WASHINGTON - Even after hundreds of Palestinian casualties and huge property damage in Gaza from deadly Israeli military strikes, the United State still hasn't called on the Jewish State, its closest ally, to stop its killing spree. "We are working toward a ceasefire that would not allow a re-establishment of the status quo ante where Hamas can continue to launch rockets out of Gaza," Secretary of State Condoleezza Rice said after briefing President George W Bush on the Gaza crisis. "Obviously, the United States is very concerned about the situation there and is working very hard with our partners around the world to address it," Rice said, noting that Bush has been in touch with major leaders of the Arab states and with the Israelis over the Israel-Hamas conflict. Asked if she planned to visit the Middle East to seek an end to the crisis, Rice replied: "I have no plans at this point." On Saturday Rice issued a statement to condemn the repeated rocket and mortar attacks against Israel and hold Hamas responsible for the new violence in Gaza.
