Cuban diplomats shouted slogans and noisily pounded tables at the United Nations on Tuesday, disrupting a meeting organised by the United States on the plight of Cuban political prisoners.

The diplomats managed to drown out the US representative, Kelley Currie, during her remarks at the UN's Economic and Social Council, prompting her to demand that security guards remove them from the hall.

The diplomats shouted "Lift the blockade of Cuba!" and "Cuba yes, blockade no". One of the protesters slammed a large book on the tables while another used a wooden mallet to drown out the US diplomat.

"Can you please remove them from the room," Currie said, pausing during her remarks.

"I'm going to pause while security removes the disruptive elements from the room."

The US diplomat later told reporters that the Cuban representatives had behaved in a "thuggish" manner that was "really shocking and disturbing."

"It makes you wonder that if the diplomats of this government behave this way, how do the police behave?" she said.

UN security guards repeatedly asked the diplomats to stop their protest, but they pressed on throughout the meeting.

The event entitled "Jailed for What?" was to draw attention to the plight of an estimated 130 political prisoners held in Cuba.

Cuban Ambassador Anayansi Rodriguez Camejo slammed the meeting as "political comedy," telling reporters that it was "based on fake arguments involving actors with dark pasts, at the service of a foreign power."
