U.S. President Barack Obama, Canadian Prime Minister Justin Trudeau and Mexican President Enrique Pena Nieto met Wednesday at the North American leader summit in Canada's capital, Ottawa.

Mr. Obama warned against isolationist tendencies in America and elsewhere.

Arguing for regional cooperation and free trade, the president said the solution to difficulties with the global economy is not to withdraw from it.

"We're gonna continue to deepen our trilateral cooperation in this hemisphere and around the world. And in short, we're gonna do more to speak with one united North American voice on the world stage." :President Obama.

U.S. Ambassador to the United Nations Samantha Power is calling on the international community to take greater action in tackling the refugee crisis.

Power spoke Wednesday at the U.S. Institute of Peace in Washington. "At the end of 2015, more than 65 million people were displaced worldwide, over half of them children. That is the highest number on record since the U.N.'s refugee agency started collecting statistics."

Power announced U.S. plans to intensify resettlement efforts to admit 30,000 more refugees in 2016 and 2017.

A new survey by the Pew Research Center shows U.S. President Barack Obama continues to get largely favorable reviews throughout much of the world in the final days of his presidency.

Fifteen of the 16 countries surveyed in Europe and Asia expressed confidence in Mr. Obama's ability to handle world affairs.

Presumptive Democratic presidential nominee Hillary Clinton got mostly favorable reviews in Europe. But, Donald Trump, the presumptive Republican presidential nominee, didn't fare as well. In many of the nations polled, his confidence rating was only in single digits.

The Italian navy Wednesday began raising the wreckage of a boat which sank [April] in April of 2015, believed to be carrying as many as 700 African migrants.

The navy has recovered more than 100 bodies, but so far, many more, including those of women and children, are believed to be locked below deck.

A refrigerated transport structure is being used so that scientists may try to identify the bodies of the victims.

Human Rights Watch is calling on the United Nations General Assembly to suspend Saudi Arabia's membership on the U.N. Human Rights Council, citing the country's leadership in a military operation against Houthi rebels in Yemen.

Human Rights Watch charges that Saudi Arabia is implicated in "numerous violations" of international humanitarian law.

Saudi Arabia has not commented directly on the statement, but in the past it has said that it is only responding to truce violations by the rebels and does not target civilians.
