Out of this conference must come not just money but a renewed commitment from everybody to work for peace that meets the aspirations of all, for Israelis, for Palestinians for all people of this region," Kerry told the conference.

"And I promise you the full commitment of President Obama, myself and the United States to try to do that," he said.

At the conference Kerry also announced an additional $212 million in U.S. aid to Palestinians in the Gaza Strip, which was badly damaged during a conflict with Israel in July and August in which 2,100 Palestinians died, most of them civilians.

An estimated 18,000 homes and vital infrastructure were destroyed in the seven-week war. The Palestinians have put the cost of reconstruction at about $4 billion over three years.

Qatar said it would provide $1 billion in reconstruction assistance for Gaza, while fellow Gulf Arab states Kuwait and United Arab Emirates promised $200 million each.

Germany on Sunday also announced it would contribute 50 million euros ($63 million) to reconstruction efforts in Gaza.

"We can't allow the people in Gaza to sink into despair," German Foreign Minister Frank-Walter Steinmeier said in a statement. The British ambassador to Egypt, John Casson, told Reuters London would provide $32 million for reconstruction.

EGYPT CALLS FOR PEACE DEAL

Egypt, which brokered the current ceasefire between Israel and the Palestinians in August, used the conference to renew its call for a wider Middle East peace deal based on a 2002 Arab initiative, which Israel has rejected.

"We should turn this moment into a real starting point to achieve a peace that secures stability and flourishing and renders the dream of coexistence a reality, and this is the vision of the Arab peace initiative," Egyptian President Abdel Fattah al-Sisi said in his opening speech.
