Pakistani Prime Minister Shehbaz Sharif praised U.S. President Donald Trump's efforts to promote peace in several parts of the world, saying Pakistan had nominated him for a Nobel Peace Prize.

Sharif made the comments as he addressed an audience of world leaders gathered in Egypt's Sharm el-Sheikh at a summit aimed at supporting the ceasefire reached in Gaza, ending the Israel-Hamas war and developing a long-term vision for governing and rebuilding the devastated Palestinian territory.

Trump’s plan holds out the possibility of a Palestinian state, but only after a lengthy transition period in Gaza and a reform process by the internationally recognized Palestinian Authority.

Israeli Prime Minister Benjamin Netanyahu opposes Palestinian independence.

Israel and Hamas came under pressure from the United States, Arab countries and Turkey to agree on the ceasefire’s first phase negotiated in Qatar through mediators. The truce began Friday.

But major questions remain over what happens next, raising the risk of a slide back into war.

The gathering reflects the international will to follow through on the deal.

More than 20 world leaders attended the summit, including King Abdullah of Jordan, Turkish President Recep Tayyip Erdogan, Qatar’s Emir Sheikh Tamim bin Hamad Al Thani, the French president and the British prime minister.

Israel and Hamas have no direct contacts and were not expected to attend.

Israeli Prime Minister Benjamin Netanyahu will not travel to the meeting because of a Jewish holiday, his office said. Trump headed to Egypt after a stop in Israel.
