Cuba Meeting Between Obama and Castro Exposes Old Grievances

HAVANA — President Obama stood beside President Raúl Castro on Monday and declared a “new day” of openness between the United States and Cuba, but old grievances and disputes over human rights marred a groundbreaking meeting and underscored lingering impediments to a historic thaw.

The two presidents, meeting at the Revolutionary Palace for the first such official contact between their two governments in more than a half-century, engaged in a frank and at times awkward exchange with each other and reporters. Mr. Obama at turns prodded Mr. Castro to submit to questions during an extraordinary 55-minute news conference.
