The president said Hamas ultimately ended the latest cease-fire on Dec. 19 and "soon unleashed a barrage of rockets and mortars that deliberately targeted innocent Israelis — an act of terror that is opposed by the legitimate leader of the Palestinian people, President (Mahmoud) Abbas."
Hamas-run Gaza has been largely isolated from the rest of the world since the Islamic militants won parliamentary elections in 2006. Then Hamas violently seized control of the Gaza Strip in June 2007, expelling forces loyal to the moderate Abbas.
Bush expressed deep concern about the humanitarian suffering of the Palestinian people in Gaza. U.N. officials say Gaza's 1.5 million residents face an alarming situation under constant Israeli bombardment, with hospitals overcrowded and both fuel and food supplies growing scarce.
"By spending its resources on rocket launchers instead of roads and schools, Hamas has demonstrated that it has no intention of serving the Palestinian people," Bush said. "America has helped by providing tens of millions of dollars in humanitarian aid, and this week we contributed an additional $85 million through the United Nations. We have consistently called on all in the region to ensure that assistance reaches those in need."
The White House has cautioned Israel to be aware of the toll its military strikes will have on civilians. Bush blamed Hamas for hiding within the civilian population. "Regrettably, Palestinian civilians have been killed in recent days," he said.
International calls for a cease-fire have been growing. Bush promised to stay engaged with U.S. partners in the Middle East and Europe and keep Obama updated. Obama is receiving the same intelligence reports on Gaza that Bush is.
Rice has spoken to both Obama and his choice for secretary of state, Sen. Hillary Rodham Clinton, about the situation at least once in the last week. Obama and Clinton have remained mum out of deference to Bush, who will be in office until Obama's Jan. 20 inauguration.
