'New day' for relations but still 'profound differences' remain

Laying bare a half-century of tensions, US President Barack Obama and Cuban President Raul Castro prodded each other on Monday over human rights and the long-standing US economic embargo during an unprecedented joint news conference.

The exchanges underscored deep divisions that still exist between the two countries, despite rapidly improved relations.

Obama, standing in Havana's Palace of the Revolution on the second day of his historic visit to Cuba, repeatedly pushed Castro to take steps to address his country's human rights record.
