Trump threatens to terminate US-Cuba deal
Donald Trump has said he will "terminate" the deal between the US and Cuba if the Cuban government does not improve the deal on offer.
President Barack Obama has worked to improve relations with the communist government in Havana, culminating in his historic visit to the island.
But the president-elect threatened in a tweet to put an end to the thaw.
His tweet came as thousands of Cubans queued to pay their respects to Fidel Castro, who died on Friday.
