US President Barack Obama plans to lift restrictions on some travel and remittances to Cuba on Monday by Cuban-Americans with family on the island, a White House official said.

"Restrictions on the families will be lifted," said the official, who spoke on condition of anonymity.

The official, who said the changes would be announced later in the day, would not say whether all restrictions on travel and remittances to Cuba by Cuban Americans would lifted, or whether they would be just partially lifted.
