WASHINGTON — The leaders of Armenia and Azerbaijan shook hands Friday at a White House peace summit before signing an agreement aimed at ending decades of conflict.

President Donald Trump was in the middle as Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan flanked him on either side. As the two extended their arms in front of Trump to shake hands, the U.S. leader reached up and clasped his hands around theirs.

The two countries in the South Caucasus signed agreements with each other and the U.S. that will reopen key transportation routes while allowing the U.S. to seize on Russia’s declining influence in the region. The deal includes an agreement that will create a major transit corridor to be named the Trump Route for International Peace and Prosperity, the White House said.

Trump said at the White House on Friday that naming the route after him was “a great honor for me” but “I didn’t ask for this.” A senior administration official, on a call before the event with reporters, said it was the Armenians who suggested the name.

Trump has sought to be known as a peacemaker and made no secret of the fact that he covets a Nobel Peace Prize. Friday’s signing adds to a series of peace and economic agreements brokered by the U.S. this year.

JERUSALEM — Israel said Friday it will intensify its 22-month war with Hamas by taking over Gaza City, stirring fears for Palestinian civilians and Israeli hostages still held in Gaza, and renewing international pressure for an end to the conflict.

Israel’s air and ground war has killed tens of thousands of people in Gaza, displaced most of the population, destroyed vast areas and pushed the territory toward famine. The timing of another major ground operation is unclear. It will likely require mobilizing thousands of troops and forcibly evacuating civilians, almost certainly worsening Gaza's humanitarian crisis.

An official familiar with the plans to take over Gaza City said the operation would be “gradual” and that there is no start date. The official spoke on condition of anonymity to discuss sensitive matters.

The U.N. Security Council announced an emergency meeting on Israel's plans was rescheduled to 10 a.m. EDT on Sunday after originally being scheduled to take place at 3 p.m. EDT on Saturday.

The U.N. Mission of Panama, which holds the council presidency this month, provided no details, but Saturday is the Jewish Sabbath and Israel is certain to want to speak at the meeting.
